Routing Metric based on Slot Length of AODV on Multihop DESYNC-TDMA

Abstract

DESYNC-TDMA is a representative bio-inspired MAC protocol which assigns slots of each node evenly in decentralized manner. However, it could suffer from bottleneck node on the delivery path because the slot is evenly assigned according to the number of neighbors in two hop range. In such a case the routing path having smaller slot length could be chosen due to its shorter hop count. This problem causes performance degradation. In this paper, we propose a routing metric using both slot length and hop count with cross-layer approach. Our scheme improves overall network performance by choosing and updating better route.
