Differentiated processing policies for near-real time and reliable traffics in ad hoc network

Abstract

This paper puts forward a differentiated processing framework for near-real time traffic and reliable traffic in a same node. As node's complexity and the contradiction of two kinds of traffic are considered, we extend packet's data structure, use multi-path minimum delay routing protocol as the sharing routing module. Retransmission in the MAC layer guarantees reliable transmission and multi-path helps to keep low delay. The MAC layer is added a notifying function to inform the upper layer of route broken. In addition, multiple queues and accessing queues pro rata in MAC layer fit for practical needs well. They are also convenient for bandwidth allocation for near-real time transmission
