self-organized capability

Mutihop Ad Hoc network, which dose not rely on fixed basic facilities and has no central control node, is a kind of distributed wireless network with self-organized capability. So it is applied to military communications, emergency rescue and the environment which can’t get the support of the cable or need temporary communications in order to handle discount wedding dresses emergencies. The expansion of voice communication, which combines image, voice and data would save cost and bandwidth, improve utilization of spectrum and be more suitable to practical blog lace wedding dresses application. However, voice transmission is very sensitive to delay and wedding gowns dresses jitter. Especially Ad Hoc network has the characteristic of distributed network, channel the flat iron shop for us sharing, self-organized, dynamic topology and so on, so the existing protocols can’t provide good quality assurance for voice transmission. Therefore, how to guarantee the quality of service of voice transmission in Ad Hoc network becomes one of the key issues.This paper mainly discount wedding dresses studies MAC protocol of multihop Ad Hoc network which was adapted to voice transmission and proposed the merging algorithm and adaptive backoff algorithm which were based on cheap ralph lauren polo shirts protocol. The adaptive backoff algorithm achieved the transporting priority of different nodes.DCF adopts CSMA/CA protocol. Because of the fairness of CSMA/CA media access mechanism, even if the bottleneck node has more voice packets in sending buffer, it needs to contend the channel.
