基于双变量泊松点过程的无线Ad Hoc网络的保密广播传输容量分析
Secrecy Broadcast Transmission Capacity of Wireless Ad Hoc Networks Based on Bivariate Poisson Point Process
摘要
Abstract
We use bivariate Poisson point process(BPPP) to model the scenario where a wireless ad hoc broadcast network coexists with a wiretapping network .By using stochastic geometry tools ,we study the secrecy broadcast transmission capacity of wireless ad hoc network ,which is defined as the product among the spatial density of broadcast transmissions without secrecy out-age ,the average number of neighbors of a broadcasting node ,and the secrecy rate .We first derive the average number of eavesdrop-ping neighbors that causes secrecy outage and then characterize the secrecy broadcast transmission capacity over general fading and Rayleigh fading channels .Finally ,numerical results are presented to show that in comparison to the case without correlation ,the cor-relation between the legitimate nodes and the eavesdroppers degrades the secrecy broadcast transmission capacity .关键词
