Path Quality Based Internet Access Scheme for Mobile Ad Hoc Network
Peng Qi · Beijing Youdian Xueyuan xuebao · 2010
A cross-layer design and path quality based adaptive scheme for mobile Ad hoc network accessing Internet is proposed. The proposed scheme adopts an integrated metric taking into account the combination of residual bandwidth,packet delivery ratio and node load to meet the needs of quality of service requirement of multimedia traffic transmissions. Furthermore,an adaptive algorithm is proposed to provide the best coverage of gateway advertisement according to dynamically adjusting broadcast range and sending interval of gateway advertisement messages in terms of gateway load and network topology. Simulations show that the proposed algorithm can effectively improve Internet connectivity performance with reasonable control overhead.
