Zigbee Cross Layer Optimization and Protocol Stack Analysis on Wireless Sensor Network For Video Surveillance

Abstract

Energy consumption is one of the most crucial design issues in wireless sensor networks since prolonging the network lifetime depends on energyefficient communication protocols. In order to improve the overall system performance of WSN an optimization technique namely cross layer design can potentially be used by way of jointly optimizing and exploiting the power consumption behavior between various layers of the protocol stack. In this paper, we propose a cross-layer framework design for the ZigBee protocol. In our paper, we describe, analyze, find the

research scope and implementation challenges for a reduced ZigBee protocol stack with a specific application, namely the wireless sensor network for video surveillance system. The final goal of this work is to implement an energy efficient ZigBee protocol stack for video surveillance system. An FSM based Zigbee power model will be used for the stack analysis.While implementing, we will also use a cross layer

power manager. First, we will implement the energyefficient protocol stack with required functionality, based on the ZigBee specifications. When the protocol stack is completed, we will refine and validate the wireless sensor network for video surveillance system.
