Identifying Design Requirements for Wireless Routing Link Metrics

In this paper, the authors identify and analyze the requirements to design a new routing link metric for wireless multi-hop networks. Considering these requirements, when a link metric is proposed, then both the design and implementation of the link metric with a routing protocol become easy. Secondly, the underlying network issues can easily be tackled. Thirdly, an appreciable performance of the network is guaranteed. Along with the existing implementation of three link metrics Expected Transmission Count (ETX), Minimum Delay (MD), and Minimum Loss (ML), they implement inverse ETX; invETX with Optimized Link State Routing (OLSR) using NS-2.34.
