Recent advancement in micro-electro-mechanical systems (mems) have enabled the development of Wireless Sensor Network (WSN) which is gaining popularity day-by-day and is used in wide range of applications. The sensor nodes that constitute WSN have several constraints like limited battery power, memory constraint, limited bandwidth etc. Therefore designing an efficient MAC layer protocol is a challenging task. TDMA-based MAC protocols can avoid collisions, overhearing and idle listening and therefore energy efficient. In this paper, the authors firstly describe a brief account of the factors influencing WSN MAC design.
