Design of Multitier Energy Efficient Secure Sensor Network

Abstract

Wireless sensor network is one of the fastest growing technology for a variety of applications. The main concern in such WSN applications is how to increase lifetime of such networks as they mostly built on sensor nodes which are typically failure-prone and have limited battery power. One of the major solution identified for this is to reduce the energy consumption, and it mainly depends on two factors as the transmission range and amount of data transferred. In this paper, a cross layer approach is used to propose an energy-efficiency and extend the life time of the sensor network which focuses on inter-working of Network and MAC layer. Along with this approach proposed Multitier Energy Efficient Secure Sensor Network (MEESSN) also introduces low cost finding protocol to save energy consumption at node level. The use of MSP 432 ultra-low power microcontroller with routing protocol in the design also enhances power usage of sensor node. At the same time in order to resolve transmission range, security and energy hole issues; low cost routing protocol and fault tolerance algorithm is used.
