Opportunistic Routing for Sensor Wireless Networks: A review

  Emadalden Alhatami

Opportunistic Routing (OR) is a new method proposed for wireless networks that increases the routing performance in wireless networks. OR leverage the overhearing in networks where transmitted packets can be overheard by more than one node or sensor. OR coordinates between these nodes that can overhear a transmitted packet. In OR, next-hop forwarders can be selected as potential candidates. There-fore, each node in OR can use multiple path to forward its packet towards the destination, where any node that overheard or in other words receives the packet may forward it towards the destination. The decision of relaying the received packets is called the coordination between candidates, where coordination takes place when multiple nodes receive the same packet and they have to decide for them-selves who gets to forward it. OR focuses on transmission reliability and throughput. In this paper, we present a brief introduction to OR protocols where it contains three main components: Routing Metric, Candidates Set Selection and Candidates Coordination. Each main component is given its own section. Lastly, a brief example of some OR protocols are given and compared with each other
