Abstract: ABSTRACT MEMORY-DECAY ASSISTED EMERGENCY ROUTING IN INFRASTRUCTURE-LESS WIRELESS NETWORKS A method for routing emergency messages in an infrastructure-less wireless network (100) comprises measuring, by a source node (102), a received signal strength indicator (RSSI) from each of a plurality of neighboring nodes (104) to generate a signal strength field. The source node (102) maintains a routing memory table (106) comprising a memory score for each route to a destination node (108), wherein the memory score decays over time according to an exponential decay function. The source node (102) calculates a combined routing score for each neighboring node (104) based on a weighted combination of the RSSI and the memory score. The source node (102) selects a next hop node from the neighboring nodes (104) based on the combined routing score and forwards an emergency packet to the selected next hop node for propagation toward the destination node (108).
