Use of Addressing Mechanism in Cluster based Wireless Sensor Network Protocol for Performance Enhancement

Abstract

The study of wireless sensor networks is such a challenging task as it is necessary to gain lots of knowledge from various disciplines. Wireless sensor network is characterized by its small size that contains sensors, transceiver, power supply, battery, microcontroller and memory. Routing algorithms, addressing mechanisms, proper balance between communication, signal processing and data processing capabilities must be found to fulfill the requirements for low device complexity together with low energy consumption. These areas motivate a huge effort in research activities. In order to efficiently construct a WSN consisting of many sensor nodes, it is necessary to apply some addressing mechanisms. When low cost small area network is required, ZigBee wireless sensor network can be used. ZigBee is an IEEE 802.15.4 wireless communication standard which specifies some addressing mechanisms. Some addressing mechanisms are distributed address assignment mechanism (DAAM), stochastic addressing assignment mechanism (SAAM), long thin wireless sensor network (LT-WSN) and distributed borrowing address assignment (DIBA). In this thesis I propose to incorporate any one clustering algorithm of wireless sensor network with an addressing mechanism proposed in ZigBee standard to enhance the performance. Performance of the sensor network will be evaluated in two cases, with implementing ZigBee addressing mechanism in our clustered wireless sensor network and without using it.
