Optimal Bandwidth Utilization in Wireless Token Ring Networks

Abstract

Wireless Token Ring Protocol (WTRP) is the medium access protocol that enables the mobile nodes to communicate in Ad-hoc networks. The major focus of Wireless Token Ring Protocol is to support mobility of nodes in ad-hoc networks. This implies the bandwidth is limited and the channel is shared among many stations. Under normal operating conditions, MAC protocol provides guarantees to achieve Quality of Service (QOS). This is achieved by Minimum throughput for each station and Medium access time for each station is bounded. To improve the performance of WTRP three different secondary message-passing techniques are proposed. These are: 1). a data packet can be sent in a reverse direction, 2). a data packet can jump to the farthest node and 3). a condition under which a secondary communication is possible within the ring.
