Qos-Energy Aware Broadcast for Heterogeneous Wireless Ad Hoc Networks

We present QoS Geometric Broadcast Protocol (QoS-GBP), a novel broadcasting protocol for heterogeneous wireless ad hoc networks. The growing number of multimedia applications over wireless ad hoc networks require low delay from network protocols and in particular from broadcasting. While broadcasting is a very energy-expensive protocol, it is also widely used as a building block for a variety of other network layer protocols. Therefore, reducing the energy consumption by optimizing broadcasting is a major improvement in heterogenous wireless ad hoc networks networking. QoS-GBP is a distributed algorithm where nodes make local decisions on whether to transmit based on a geometric approach. QoS-GBP enables a tradeoff among the need for neighborhood information (communication overhead) and the delay. QoS-GBP is scalable to the change in network size, node type, node density and topology. Through simulation evaluations, we show that QoS-GBP is very scalable and guarantees minimum delay.
