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.

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: 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.

Description: we have discussed HCTA based tracking and single hop routing and LEACH based
tracking and clustering routing. LEACH based tracking is divides sensor nodes in cluster. In each
cluster CH (cluster head) applies aggregation process on packets then directly transmits to sink node.
Thus, minimum packets transmit and packets does not route entire sensor nodes in WSN. CHs in
clusters transmit packets based on carrier sense multiple access collision avoidance (CSMA/CA), to prevent collision and minimize transmission and reception process. Overall energy conserve by LEACH during simulation is same.

Description: Monitoring applications define an important
class of applications used in wireless sensor networks.
In these applications the network perceives
the environment and searches for event
occurrences (phenomena) by sensing different
physical properties, such as temperature, humidity,
pressure, ambient light, movement, and presence
(for target tracking). In such cases the
location information of both phenomena and
nodes is usually required for tracking and correlation
purposes. In this work we summarize most
of the concepts related to localization systems for
WSNs as well as how to localize the nodes in
these networks (which allows the localization of
phenomena). By dividing the localization systems
into three distinct components — distance/angle
estimation, position computation, and localization
algorithm — besides providing a didactic
viewpoint, we show that these components can
be seen as subareas of the localization problem
that need to be analyzed and studied separately.

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.

habitat monitoring in nature preserves, monitoring and gathering events in hazardous environments, surveillance of buildings, and
surveillance of enemy activities in a battlefield environment. Nodes in a sensor network are severely constrained by energy, storage capacity and computing power. To prolong the lifetime of the sensor nodes, designing efficient routing protocols is critical.

Description: In wireless sensor network, residual energy of node is very important criteria. Life of wireless sensor network depend the energy of node. In most of the application, the nodes are battery operated. So it is very important to select the parameters like nodes deployment in network, size of packet, etc. In work,analyze node’s energy with respect to packet size, distance, time and also how much data can be transmitted. And finally we will conclude for the effective value of these parameters.
