Contention avoidance with hop based priority in 802.11e multi-hop network

Wireless multi-hop networks offer lower network bandwidth and longer delay than wireless single-hop networks because of contention. We propose hop based priority (HBP) technique using 802.11e to minimize contention. The HBP technique increases priority in media access control (MAC) by each hop. It makes higher priority at the previous or early sent packet than the next or later sent packet. We validate by modeling and show by simulation that HBP technique can perform 31% better.
