General Lower and Best Case Upper Bounds on Energy Optimal Multicasting in Wireless Ad Hoc and Sensor Networks

Wireless ad hoc and sensor networks consist of small battery driven devices which communicate wirelessly without using a pre-installed network infrastructure. Regulatory and physical constraints prevent nodes from reaching all other nodes in one single communication hop. Moreover, multi-hop communication can be useful when the total energy consumed should be kept low. The fact that signal attenuation - and with it the communicating nodes' energy consumption - grows more than linear with increasing communication range suggests that long distance communication should be performed with the help of a sequence of intermediate relay nodes.
