Balancing Energy Consumption to Maximize Network Lifetime Using Particle Swarm Optimization in Wireless Sensor Networks

A Wireless sensor network of globally distributed autonomous sensors to monitor physical or environmental conditions such as temperature, noise, pressure etc. and to cooperatively pass their data through the network to a main location. CASER protocol is used to increase the lifetime of the network. Energy consumption and security are the two conflicting issues in WSN. To overcome this problem some parameters are used Energy balance control using PSO (Particle swarm optimization) and lifetime optimization TORA(Temporally ordered Routing Algorithm). For security Probabilistic random walking. The proposed protocol can achieve a high message delivery ratio while prevent routing from polluting attacks.
