Two way of Round Robin MAC Protocol for Clusterheads in WEAC for MANETs

A wireless mobile Ad hoc network (MANET) is a collection of wireless mobile hosts forming nodes that are arbitrarily and randomly changing their locations and communicating without the aid of any centralized administration or standard support services. In cluster-based routing protocols, a dusterhead is elected from a set of nominees, based on an agreed upon rule, to act as a temporary base station within its zone or autonomous system. Mobile stations elected as clusterheads are used to track other mobile stations in the ad hoc network. In each cluster, we use the dusterhead controlled token to assign the channel among contending Mobile Terminals (MTs). dusterhead controlled token supports multiple classes of service and minimizes collisions. In this paper, we describe briefly the operation of the Warning Energy Aware dusterhead (WEAC) and the Virtual Base Station On-demand (VBS-O) protocols, and then we compare the performance of the clusterheads of WEAC infrastructure creation protocol using two polling methods, namely: exhaustive polling and partially gated polling, by means of simulations.
