Abstract

The consequence of simultaneous transmissions by nodes in inter-working multi-hop wireless networks is inter-node interference. Inter-node interference is a metric that is important for the performance evaluation of inter-working wireless networks. Several interference models exist in literature, however, these models are for specific wireless networks and MAC protocols. Due to the heterogeneity of link-level technologies in inter-working multi-hop wireless networks, it is desirable to have generic models for the evaluation of interference on links in such networks. A generic model can provide information about the interference level on a link irrespective of the MAC protocol in use. This paper presents a generic interference model. The model evaluates the probability of interference and uses the negative second moment of the distance between a receiver-node and interfering-nodes to evaluate the interference power on a link in an inter-working multi-hop wireless network. Numerical results of the performance of the model are presented.
