Title
A 2-Hop Path Selection Protocol (2psp) In Multi-Rate Ad Hoc Wireless Networks
Abstract
We develop an enrichment protocol, called a 2-hop Path Selection Protocol (2PSP) for a set of nodes, in which data can be sent faster using adaptive rate control capability of IEEE 802.11 a/b/g MAC protocol via a relaying concept than via a direct connection. The main objective of this protocol is to build upon opportunistic rate adaptation in order to assist a sender, a relay node, and a receiver to reach a higher rate data transmission through Medium Access Control (MAC) layer relaying. We propose a relay mechanism to further improve the performance of 2PSP protocol. In the relay mechanism, new contention window, called a Short Backoff Internal (SBI) is applied for a set of relay nodes. A potential node that succeeds as a relay is allowed to send a Ready-To-Relay (RTR) message. In this paper, two collision resolution algorithms are proposed to deal with the case when the potential relay node is more than one. Simulation results indicate that the proposed 2PSP protocol can achieve high reduction of delay and power consumption and also an improvement in the throughput compared to both Receiving-based Auto Rate (RBAR) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocols.
