Synchronous Duty Cycle in MAC protocol for Wireless Applications

WSN stands for wireless sensor networks. The major difference with ad hoc networks is that WSN supports one to one, many to many, one to many and many to one node communicate between them. However, energy consumption, and network lifetime are always a challenge in WSN. In this paper, we have used a synchronous variable duty cycle MAC to create infrastructure for WSN and communicate synchronously in single-hop and multi-hop scenarios with different data rates in different paths to attain better performance in delay, energy, lifetime, throughput. Simulations are carried out using NS-2.35.

1. INTRODUCTION

Cooperative Communication at MAC Layer is analyzed in [5]. Frequency Domain Contention and Polling MAC is studied in [4]. S-MAC Protocol, Analytical Model is simulated in [7]. Synchronous Duty Cycle reservation-based MAC Protocol named OCMAC in [2]. Analytic Hierarchy Process (AHP) in [1]. Layering and a Distributed Clustering algorithm is used in [3]. (VAT-MAC) Adaptive Time Division Multiple-Access based MAC protocol for VANETs are analyzed by authors in [11]. Comparative analysis of two MAC protocols namely RI MAC and receiver initiated MAC with contention based asynchronous duty cycle protocol, ATMA, advertisement based TDMA MAC protocol are verified in [10].
