简介
Packet delay control in mobile ad hoc networks (MANETs) is critical to support delay-sensitive applications in such networks. By combining erasure coding and packet redundancy techniques, this paper proposes a general two-hop relay algorithm 2HR- for a flexible control of packet delivery delay in MANETs, where a group of x packets in source node are first encoded into encoded packets based erasure coding, and each encoded packet is then delivered to at most f distinct relay nodes (f-cast) that will help to forward the encoded packet to destination node. To understand the delay performance in a 2HR- MANET, we then develop a discrete time multi-dimensional Markov chain model to depict the packet delivery process in the network, based on which closed-form results on mean and variance of packet delivery delay are further derived. Finally, extensive simulation and theoretical results …
