A Unified Metric for Opportunistic Routing in Wireless Mesh Networks

چکیده
In wireless mesh networks, the routing of packets from source to destination is crucial and challenging task. The wireless mesh networks find applications in disaster management, video on demand, intelligent, health care systems, etc. Various routing protocols exist in literature to improve the efficiency of the wireless mesh networks calculated in terms of reliability, cost, throughput, error rate, etc. The opportunistic routing proves to be more efficient protocol best suited for wireless mesh networks as it avoids duplicate transmission and improves performance of the network. The routing metrics are essential to evaluate the best possible path for packet delivery. This paper conveys the essence of the existing metrics used for analyzing the routing protocol considered for evaluation. Further we introduce a new opportunistic routing metric called Unified Expected Distance Progress with Successful Transmission Rate (UEDPSTR) which is compared with the characteristics of the network. Index Terms — Metric, Opportunistic Routing, Wireless Mesh Network.

Opportunistic routing has been widely approved because of its throughput improvement for wireless mesh networks; however, few researches focus on transforming its benefit into realizing energy efficiency for wireless sensor networks (WSNs). We notice that two common issues in fixed-path routing schemes, including single-path routing or multi-path routing, are that (1) a path may traverse throug...
متن کاملSelf-Interference Aware Opportunistic Routing Metric in Wireless Mesh Networks
In this paper, we present a novel routing metric named SIOR which is designed for opportunistic routing in single-rate wireless mesh networks. Most of the existing routing metrics either assume too pessimistically that all links within the network interfere with each other or do not consider intra-flow interference at all. In fact, any flow which has its destination node at least two hops away ...
