    Abstract: In wireless sensor network, security and energy efficiency is the main issue during transmission of
the packet. In order to overcome these issues, a cluster based routing architecture using PSO for ZigBee mobile
wireless sensor networks is proposed. In this studr, first clustering is done based on Particle Swarm
Optimization (PSO) technique. The selection of best emissary node is done based on PSO technique to increase
the number of reliable node in the cluster. To maintain the energy efficiency, modelling of sleep period is done.
To increase the security during transmission, each information is encoded using channel coding with XOR
operation.
