Abstract
In this chapter, we investigate connectivity of large wireless networks in the presence of interference. Different from previous chapters where connections are assumed to be independent, the presence of interference implies that signals transmitted at the same time will mutually interfere with each other. Hence, connections become mutually correlated. Specifically, consider the extended network model and the SINR connection model, we establish a sufficient condition and a necessary condition, i.e., an upper bound and a lower bound, on the transmission power required for a network adopting the carrier sense multiple access protocol to be asymptotically almost surely connected. The two bounds differ by a constant factor only. It is shown that the transmission power only needs to be increased by a constant factor to combat interference and maintain connectivity compared with that considering a unit disk connection model without interference.
