Description: Wireless Sensor Networks are wireless networks where every nodes recolects surrounding information. WSNs have several aplications such as militar survival, traffic control, building security, scientific research in other planets, etc. This project presents a communication protocol for wireless sensor networks based on the ant colony optimization metaheuristic, which uses artificial ant agents that recolects data from all sensor nodes of the network. Every ants fuzes data from a node and sends it to every other sensor and then to the base station. All ants look for a way to go where there is an energy eficient path. Platform: |

Description: The need to reprogramme a wireless sensor network may arise from
changing application requirements, bug fixes, or during the application
development cycle. Once deployed, it will be impractical at
best to reach each individual node. Thus, a scheme is required to
wirelessly reprogramme the nodes. We present an energy-efficient
code distribution scheme to wirelessly update the code running in
a sensor network. Energy is saved by distributing only the changes
to the currently running code. The new code image is built using
an edit script of commands that are easy to process by the nodes.
A small change to the programme code can cause many changes to
the binary code because the addresses of functions and data change.
A naive approach to building the edit script string would result in
a large script. We describe a number of optimisations and present
experimental results showing that these significantly reduce the edit Platform: |

Description: Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes. In order to reduce the entire energy consumption of the WSN, a promising approach is to design light clustering algorithms.LEACH is such a well-known clustering algorithm that was designed to distribute the energy consumption to nodes in the WSN evenly. LEACH is characterized by its attactive clusterbased strategy however, in the algorithm, energy dissipation of
entire network is still great during the process that cluster-heads (CH) transmit data to base station (BS). In this paper, based on
LEACH, we propose a modified clustering orithm which is named ESCAL. In ESCAL, CHs won’t communicate with BS directly, but transfer aggregated data to the nearest node in term
of received signal strength then this elected nearest node willcompress and forward the data to BS.-Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes.

Description: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency.
Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In
this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the
cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.

Description: The proposed routing protocol for Wireless Sensor Network is hierarchical and cluster based. The protocol supports mobility in the Sensor Nodes as well as in the Sink. The entire
protocol is described in terms of two phases namely Setup Phase and Data Forwarding Phase. After deployment of the Sensor Nodes entire sensor field in divided into some logical clusters and each cluster contains Sensor Nodes with different roles such as Gateway Node, Cluster Head Node and Ordinary Sensor Node.
Majority of the computation intensive tasks are carried out in the Sink. Simulation results show the energy efficiency of the proposed protocol. The performance of the proposed protocol
has been compared with that of CBR mobile WSN and results show better performance of the proposed protocol. Future scope of the work is outlined. Platform: |

Description: In wireless sensor networks, the power resource of
each sensor node is limited. Minimizing energy dissipation and
maximizing network lifetime are important issues in the design
of routing protocols for sensor networks. In this paper, Cluster
routing protocol LEACH (Low-Energy Adaptive Clustering
Hierarchy) is research and improved. We extend LEACH
stochastic cluster-head selection algorithm via changing the
round time According to the situation of sensor network. It is
named Variable-round LEACH. The result simulated in NS2
shows that the energy is significantly reduced and the lifetime
of the whole network is increased compared with the previous
routing algorithm for the sensor networks. Platform: |

Abstract:In sensor networks,sensor nodes collect local data and transfer these data to the base station often relayed by other
nodes.Therefore sensor nodes that are nearer to the base station will consume more energy. If deploying sensor nodes in
general way, i.e. deploying nodes uniformly in the network, sensor nodes nearby the base station will use up energy soon and
the base station can t collect data anymore. This paper presents a density function to deploy sensor nodes through investigating
energy consumption in wireless sensor network. Theoretical analysis and simulation result show that deploying by method of
this paper improve system lifetime to times of deploying uniformly, where t is radio distance of sensor node and R is radius of
the region of deploying sensor nodes.

Description: Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method. Then we investigate the node self-localization methods. Since the widespread adoption of the wireless sensor network, the localization methods are different in various applications. And there are several challenges in some special scenarios. In this paper, we present a comprehensive survey of these challenges: localization in non-line-of-sight, node selection criteria for localization in energy-constrained network, scheduling the sensor node to optimize the tradeoff between localization performance and energy consumption, cooperative node localization, and localization algorithm in heterogeneous network. Finally, we introduce the evaluation criteria for localization in wireless sensor network. Platform: |
