Abstract

Recent advancements in wireless communications and electronics have enabled the development of low cost sensor networks. Among the protocols of wireless Sensor Networks (WSN), Medium Access Control (MAC) protocols are given more priority as traditional MAC protocols are not suitable for Wireless communication. As many of the MAC protocols consider the sensor nodes to be stationary, and when these protocols are used in mobile environment the network performance decreases. In this paper, we introduce a new TDMA based MAC protocol which can be used in mobile wireless sensor network. This protocol uses TDMA based MAC scheme where the time will be divided into frames and then time slots. These slots are further divided into sections as channel request (CR), channel allocation (CA) and data section. We will also design an algorithm considering the energy efficiency of a wireless sensor network. Therefore the life time of the sensor nodes deployed in a wireless sensor network will be increased.
