SRA: A Salmon-Like Approach to MANET Routing

Abstract

Wireless mobile ad-hoc networks are characterized by the lack of physical connections. Due to the mobility of nodes, interferences, multipath propagations and path losses, they do not exhibit a fixed topology; hence, dynamic routing protocols are required. In recent years, new approaches inspired by nature have been tried: among them, particular interest has been raised by ants and bees colonies. The characteristics inherited by the collective behaviors of social insects empower algorithms with features such autonomy, self-organization, adaptivity, robustness, and scalability. Here, we propose a salmon-based approach, that, although different since salmons do not show evidence of social behaviors, suggests interesting cues to solve the routing problem when observing salmons in their way from the birth river to the sea, and back at the spawning time.
