Route establishment in MANETs; Ameliorated with Tunicate Swarm Algorithm and Cross layer Interaction

This paper proposes directional routing approach in Mobile Ad-hoc NETworks (MANETs) that explores updated biologically inspired intensification method called Tunicate Swarm Algorithm (TSA) to identify optimal path. TSA that duplicates jet impulse and swarm actions of tunicates is modified to overcome its earlier deficiency of trapping into local optima. Network density parameter is exchanged across layers using Cross Layer Interaction (CLI). It is proposed to reduce routing protocol’s burden by having changing directional monitoring time, optional handshake and changing data fragment length in medium access protocol of directional antenna enabled MANETs. The results obtained in simulation show that TSA and CLI based routing approaches in MANETs provide improved result in relation to other competing proposals.
