Mobility-Based Real Time Communication in Wireless Sensor Networks

Abstract

Wireless Sensor Networks face unavoidable challenges in the areas of connectivity, network lifetime and energy efficiency in its implementation. At the same time, urgent data captured by the sensor nodes need to be processed at real time with low message latency and maximum utilization of the bandwidth. This paper presents an in-depth analysis of the different data transfer methods available under mobile platform and a performance analysis of different real time bandwidth allocation schemes in a Wireless Sensor Network. An optimal solution for the communication in mobile platform is analyzed and found out to be the Rendezvous based solution implemented with Relayed Data Collection Algorithm to achieve an acceptable value of network lifetime and energy consumption. In case of real time communication, the optimal time slot bandwidth allocation scheme – O-TDMA has been proved to have met all the performance parameters and found out to be the optimal solution in real time communication in a Wireless Sensor Network. We propose to couple these two optimal solutions (the Rendezvous based solution implemented with Relayed Data Collection Algorithm to gain optimum mobility and the O-TDMA to gain optimum real time communication) to create an efficient and effective real time communication in a mobile platform
