Abstract

Abstract

It is adopted the wireless channel, limited battery energy and distributed control techniques in wireless Ad hoc networks, so the existing questions are channel safety threat and more power consumption. To solve above questions, we develop a joint source and channel virtual user safety identification method for DS-CDMA wireless Ad hoc networks. The method can protect and encrypt the header by embedding a random, safe and identifiable header. A subspace-based multi-user detection and virtual user safety identification method can be used at receiver nodes, and the virtual user safety identification method only identifies the header information. Simulation results show that our proposed scheme improves miss rate and active user estimation precision, reduces the probability of retransmission, then saves running radio module power consumption, achieves virtual user safety identification and obtains advanced channel safety.
