Recently, there has been a significant increase in research of wireless sensor networks (WSN). Network communication requirement of WSN is different from that of the traditional network because the traditional performance criteria of network are throughput, latency and fairness, whereas in WSN, energy efficiency become more important. Making a system energy efficient in WSN is a challenging research topic and researchers have developed many algorithms [1,2,3].
In this paper, we propose an analytical model of IEEE 802.15.4 which is standardized toward low complexity, low power consumption and low data rate wireless data connectivity. This standard allows two network topologies: star and peer-to-peer. In a star topology, every sensors must communicate through PAN coordinator. In a peer-to-peer topology, all devices can communicate each other if both devices are within a physical range. In a star topology, network uses two types of network channel access mechanism. One is based on the slotted CSMA/CA in which slots are aligned with the beacon enabled. Another access mechanism is based on the un slotted CSMA/CA without beacon frame.
