Content forwarding strategy based on ICN architecture in VANET
Published 2017-05-01“…Combining VANET with ICN,a routing building and selecting strategy-SRBS based on vehicular dynamic parameters was proposed.After locating the content nodes through content discovery process,several unicast forwarding paths would be built,which reduces useless traffic compared with a flooding way.By introducing dynamic metrics and LET to routing building and selecting process,SRBS improved the link stability and reliability,which ensured the Data’s successful return.Simulation results show the scheme also improves the time tolerance of routings and makes full use of network cache and reduces delay and routing hops.…”

Study of energy efficient WBAN topology optimization in IEEE 802.15.6
Published 2016-06-01“…An optimization model was proposed to design the network topology of wireless body area network(WBAN).Focusing on the two hops extended star topology given in IEEE 802.15.6 standard,a mixed integer non-linear programming model was constructed to minimize the energy consumption of WBAN.Then,the optimized network topology was obtained by adjusting the number and location of relays to be deployed and the data routing towards the hub.The experimental results show that,compared with Elias’s model (EAWD,energy aware WBAN design),the proposed model can reduce network energy consumption by 40.5%,decrease network delay by 52.4% on average,and extend network lifetime by double.…”

Node centrality metric based caching mechanism in content-centric network
Published 2017-06-01“…In order to reduce the cache redundancy as well as increase the cache hit ratios in content-centric networks,the node centrality metric based caching mechanism (CMC) was proposed.CMC utilized controllers to obtain the topology of the whole network and the idle rate of cache space.According to the connection relation of the topology,the degree centrality,closeness centrality and betweenness centrality of nodes were calculated.When CMC choose the caching nodes,it took the three metrics and the idle rate of cache space into account.Simulation results show that CMC can effectively increase the cache hit ratios and reduce the content fetching hops and average request delay compared with the traditional routing algorithms in CCN.…”

Analysis of stability condition for LDPC codes and optimizing degree sequences over mixed channel
Published 2016-09-01“…Under the circumstance that white Gaussian noise and random erasures exist all at once,the stability condition for LDPC codes over mixed channel was proposed.And it was proved that a good degree sequence of LDPC codes was not optimized over mixed channel.It can also be proved by simulation.The random particle swarm optimization (RPSO) and simulated annealing (SA) algorithm were combined to find some capacity-approaching degree sequences over mixed channel with different erasure probabilities.The threshold of signal-to-noise ratio improves 1.615 9 dB than that of the classical degree sequences calculated by Gaussian approximation over mixed channel.These degree sequences are optimal for optical recording and frequency-hopping communication with narrow-band interference.…”

Link duration probability based cross-layer routing protocol for epoch-based movement
Published 2010-01-01“…The end to end transmission performance is very poor because of routing failure caused by node movement in MANET.To solve this problem,an algorithm for the link duration probability of epoch-based movement was proposed,and based on which a link duration probability based cross-layer routing protocol for epoch-based movement(LPCP) was proposed.LPCP cross-layer interacts with transport layer,and considered both the maximum path availability and the minimum hops of an end to end connection.Three complementary mechanisms:routing switch,save then forward,ack reconfirm were proposed to prevent routing failure and the transmission efficiency reduction.It is shown by computer simulation that LPCP results in a significant improvement of the packet loss caused by routing failure,and increase the throughput much more.…”
