摘要：
In this paper, we characterize analytically the multi-access interference in wireless code-division multiple-access 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 signature code length and receiver design on the network performance for different topologies is also studied.
