Abstract

Performance analysis of wireless sensor networks in terms of data transmission capacity and lifetime of the networks are critical research issues towards the design of optimal deployment strategies of the sensor networks. In contrast to other types of wireless networks, nodes in wireless sensor networks are densely deployed and organize themselves in an ad hoc fashion. Due to limited transmission ranges, any two nodes cannot reach each other directly and rely on other sensor nodes to relay data between them. Hence, the data packets between the source and destination are routed through multi-hops. Besides, sensor nodes are normally small in size and have constrained energy sources. Hence energy consumption analysis is an important performance measure in wireless sensor networks. In this chapter, the contention free and contention based channel access mechanism in wireless sensor networks is discussed. Considering different MAC mechanisms in wireless sensor networks, mathematical models for the energy consumption issues are analyzed.
