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: Wireless sensor networks (WSN) consist of small
self-contained devices with computational, sensing and wireless
communication capabilities. They allow flexible, powerful, tetherless,
automated data collection and monitoring systems to be
created. Anticipated applications include environmental hazard
monitoring, forest fire detection, machine instrumentation, etc.
Many routing protocols have been proposed to facilitate data
transport from sensor nodes to a base station few of these protocols
have been formally verified or operationally deployed however.
The Minimum Cost Forwarding (MCF) routing protocol[1],
has been proposed. The application of MCF is restricted to
networks possessing a single sink node and multiple source
nodes.-Wireless sensor networks (WSN) consist of small

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: The sensor networks application domain continues to increase with the need for an
effective security mechanism. The fact that WSN often deal with sensitive data operating in
hostile and unexpected environments, makes the concept of security considered essential.
However, because of limited resources and low computing capacity of a sensor node, the
development of a mechanism that ensures security is a real design challenges.
In this report we have tried to propose a new security mechanism dedicated to WSN. Our
main objective is to secure the process of transferring data to the base station. The proposed
protocol protects transferred data against intruder nodes attacks, using a security
mechanism based on the use of control message MAC (Message Authentication Code) for
authentication. Our protocol performances are evaluated using the simulator NS2.

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.
