    Research of connectivity for wireless sensor networks by HUANG Xiao 1, CHENG Hong-bing 1, YANG Geng1

    Published 2009-01-01
    “…It was crucial to acquire the knowledge of nodes connectivity before management,application and research of wireless sensor networks when they had been deployed in the interest randomly.Under real environment there can be some nodes called unreachable node in interest,which could not communicate with base station for some reason,for ex-ample there are some nodes lie out of the radio range of base station or the interest range.A scheme to make those un-reachable nodes be able to communicate with base station was proposed.At the same time,a judgment algorithm for nodes connectivity based on a normal wireless sensor networks model was proposed.In simulation two-experiment scheme to test the proposed scheme and judgment algorithm were set.From the results of simulation conclude that the proposed scheme can improve nodes’ connectivity in the interest and the proposed algorithm can judge the connectivity efficiently and accurately.…”

    Performance analytic model and method for CCF multi-channel mechanism by YAN Jun-rong, ZHANG Shun-yi, SUN Yan-fei, LI Jun

    Published 2009-01-01
    “…According to the characteristics of common channel framework(CCF) multi-channel mechanism of 802.11s draft,a performance analytic model and method were proposed.Considering two states of assigning or no assigning common channel to transmit data existed in CCF,two performance analytic models based on common channel were proposed and throughput formulas were deduced,furthermore condition of state transition was presented.There were four parameters,such as data rate,payload,number of channels and number of stations,participating in the simulation of throughput.The simulation result shows that with increasing of data rate,increasing of number of stations and/or decreasing of payload,the number of channels needed decreases as state of assigning common channel transiting to state of no assigning common channel,and then the throughput of CCF reaches the maximum.…”

    Published 2015-06-01
    “…The topology of mobile underwater wireless sensor networks (MUWSN) evolves dynamically with ocean currents,which will have great impact on network performance.To solve this problem,a topology optimization method for MUWSNs is proposed based on topology reconfiguration.Firstly,the proposed method optimizes the coverage rate of MUWSNs by adjusting the location of sensor nodes through simulating fish behaviors.Secondly,to optimize the connectivity of MUWSNs,the proposed method repairs disconnected positions and eliminates key nodes in MUWSN through using redundant nodes.Finally,simulation results verify the rationality and validity of the proposed method.Experimental results show that the algorithm can guarantee the network coverage is maintained at about 97%,connectivity rate above 89%,with lower energy consumption.…”
