Abstract
A battery-powered node within a wireless mesh network performs energy-aware packet routing based on multiple factors. The battery powered node computes, for a given link to an adjacent node, the energy needed to transmit a packet to the adjacent node. The battery-powered node also determines the amount of battery energy remaining in the adjacent node. Based on these two factors, the battery powered node computes a link cost associated with the link to the adjacent node. The battery-powered node performs a similar computation for all adjacent nodes and then forwards packets via these adjacent nodes based on the associated link costs. The battery-powered node also maintains a table of routes through adjacent nodes, and reroutes packets through different adjacent nodes in response to link failures.
