Abstract
Modern wireless communication system based on wireless sensor network is strictly depends on medium access mechanism to improve its performance. CSMA is modifying here in its CSMA/CA format and trying to enhancing its performance same as CSMA/CD has for wired network. The aim of the paper is to inform how optimization of CSMA based sensor network is possible and how we can deploy it for monitoring of different areas like deployment of bomb plantation by terrorists etc. Security requirement like confidentiality, integrity and authentication can be achieved by CBC-X that facilitates encryption/decryption and authentication of packets on a one pass operation for link layer security.
