Cooperative behaviour of location aware nodes in ad-hoc networks

Abstract

This paper presents a method for packet delivery around voids in ad-hoc networks that use geographic forwarding. The use of local cooperative behaviours to transport packets around network voids features no global coordination. By changing goals, an individual node can create or join in a transient group that generates and holds local knowledge of the void, and which triggers modified behaviour for packet delivery. It is envisaged that additional behaviours may be developed to handle network operation at multiple protocol layers.
