Abstract
Multipath routes in wireless multihop ad hoc networks have proven to increase performance compared to single path routing when providing backup paths in case of path failures and also distributing flows (i.e. data traffic) among several paths. The drawback of using multipath simultaneously in wireless multihop ad hoc networks is that the other nodes in the network located in the other active paths may interfere with their own communications, degrading the effective throughput.
This work proposes an analytical model to find multiple non-interfering routes or routes with minimum interference between a source and a destination in a given network topology. These types of routing paths are called Radio Disjoint Multipath (RDM) routes. Compared to the previous work, this work pioneers the use of models to determine interference free routes in a wireless multihop ad hoc network considering two criteria: the mutual interference of each path and the background traffic load of the path. Further, simulation results are taken by implementing RDM routes in 802.11 based multihop ad hoc networks. Both analytical and simulation results are obtained and analysed for different network scenarios that use RDM routes by distributing packets of a single flow among multiple RDM paths. Analytical results show that the sustainable throughput can be doubled when using RDM paths for unidirectional flows. Simulation results also show that throughput can be improved with RDM routes by a factor of 1.5 and 1.8 in some cases, when using uni-and bidirectional UDP flows, respectively.
