Abstract

In this paper, we characterize analytically the multiaccess interference (MAI) in wireless CDMA sensor networks with uniformly random distributed nodes and study the tradeoff between interference and connectivity. To provide a guideline for improving system behavior, three competitive deterministic topologies are evaluated along with the random topology in terms of link-level and network-level (routing) performance. The impact of the signature code length and the receiver design on network performance for different topologies is also studied.
