Description: Wireless Sensor Networks (WSN) is different than the Cellular Networks as I mentioned earlier.
A WSN is composed of a large number of sensor nodes that communicate using a wireless medium (air).
The sensor nodes are deployed randomly in the environment to be monitored.
The sensor nodes distributed in ad hoc structure.
In WSN there is no base station and not all nodes hear each other.
The WSN is a multi-hop network.
Basic part of my code is to randomly place the sensor nodes in the given space then connecting each two nodes if the distance between them less than or equal to the communication radius. Platform: |

Description: In this paper we simulate a multi-hop self-organizing wireless
sensor network. The purpose of the simulation is to investigate,
quantitatively, the performance of our self-organizing network
design. In particular, we examine such parameters as network
formation time, data packet delivery performance, throughput,
and device duty cycle. In addition, we analyze the impact of
MAC and low-duty cycle protocols. We demonstrate that our
tree network has the capability of automatic network formation,
update, and recovery. The design also supports simple address
assignments and straightforward routing. We discuss our
approach, OPNET simulation design, and simulation results Platform: |

Description: The sensor nodes of a wireless grain depot
surveillance system are deployed in crystal grids, which provide
lot of valid position information. To avoid the energy
consumption unbalance of the single hop routing model adopted
by LEACH protocol, a novel hybrid routing model is proposed
in this paper. Multi-hop routing is introduced into the distant
field nodes through right angle transferring of approximate
equivalence consumption path. And the average energy
consumption is used as a threshold of selecting intermediate
transferring nodes to minimize total variance of node s energy
consumption, so that balance the whole network. Simulations
show that the hybrid model eliminates hot spots within cluster
and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot

Description: Advances in wireless sensor network (WSN) technology has provided the availability of small and low-cost sensor nodes with capability of sensing various types of physical and environmental conditions, data processing, and wireless communication. Variety of sensing capabilities results in profusion of application areas. However, the characteristics of wireless sensor networks require more effective methods for data forwarding and processing.
In WSN, the sensor nodes have a limited transmission range, and their processing and storage capabilities as well as their energy resources are also limited. Routing protocols for wireless sensor networks are responsible for maintaining the routes in the network and have to ensure reliable multi-hop communication under these conditions. In this paper, we give a survey of routing protocols for Wireless Sensor Network and compare their strengths and limitations.

Description: Wireless sensor networks with mobile sink are ex-pected to increase the flexibility for gathering information in large-scale sensing and detecting environments. Energy saving becomes one of the most important features of the sensor nodes to extend their lifetime in such networks. A novel tree-based power saving scheme is proposed in this paper to reduce the energy consumption in wireless sensor networks with mobile sink. We adopt a dynamic sorting algorithm to create a tree-cluster routing structure for the sensor nodes. The main goal of this scheme is to reduce the data transmission distances of the sensor nodes by employing the tree structure and multi-hop concepts. Based on the location of mobile sink, the distances between the sensor nodes, and the residual energy of each sensor node, the proposed scheme makes an efficient decision for creating the routing structure. The energy consumption is reduced and the lifetime is extended for the sensor nodes by balancing the network load. Platform: |

Description: Routing protocols in Wireless Sensor Networks (WSNs) emphasize on data dissemination, limited battery power and bandwidth constraints in order to facilitate efficient working of the network, thereby increasing the lifetime of the network. In this paper, the authors present an Energy Aware Multi-hop Multi-path Hierarchical routing protocol (EAMMH). EAMMH protocol organizes the sensor nodes into clusters and forms a multi-hop intra-cluster network. It establishes multiple paths each sensor node to the cluster head and provides an energy aware heuristic function to choose the optimal path.-Routing protocols in Wireless Sensor Networks (WSNs) emphasize on data dissemination, limited battery power and bandwidth constraints in order to facilitate efficient working of the network, thereby increasing the lifetime of the network.
