Topology and Link Quality-aware Geographical Opportunistic Routing in Wireless Ad-hoc Networks
Opportunistic Routing (OR) takes advantage of the broadcast nature and spatial diversity of wireless transmission to improve the performance of wireless ad-hoc networks. Instead of using a predetermined path to send packets, OR postpones the choice of the next-hop to the receiver side, and lets the multiple receivers of a packet to coordinate and decide which one will be the forwarder. Existing OR protocols choose the next-hop forwarder based on a predefined candidate list, which is calculated using single network metrics. In this paper, the authors propose TLG - Topology and Link quality-aware Geographical opportunistic routing protocol.
