    Joint power control for untrusted relay cooperation-based confidential communication by Wen-jiang FENG, Wei-heng JIANG, Yi-na DENG, Yang YUAN

    Published 2014-11-01
    “…The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure communication between BS and multiple MS,destination-based jamming (DBJ) scheme was adopted.With the assumption that all MS had fixed transmit power,the joint UR and BS power control which aims at maximizing system sum secrecy rate was discussed.For this problem,analysis indicated that it was equivalent to joint access control and power allocation problem thus its NP-hard.Through problem relaxation,a suboptimal MS access control and alternatively power allocation algorithm was provided.This algorithm is proved to have polynomial complexity and can converge to at least a suboptimal solution for original problem.Simulation results show that compared with the benchmark algorithms,the proposed suboptimal algorithm is better in the achievable secrecy rate performance.…”

    A Strategy Based on Cooperative Transmission for Minimizing Delivery Delay in WSN by Qingyu Yang, Xinyu Yang, Yu Wang, Dou An

    Published 2013-11-01
    “…To minimize the delay caused by sleeping nodes in the transmission path, we propose to “hop over” the sleeping nodes based on the range extension of cooperative transmission (CT). The transmission delay models for the random duty-cycled WSN and optimized fixed duty-cycled WSN under cooperative operation are formulated, and an algorithm named (delay-tolerant cooperative transmission DTCT) is presented for the selection of transmission modes to avoid waiting for the sleeping nodes to wake up. …”
