An Consistent Routing Policy Based on Ant Algorithm in Software Defined Networking by Yuwei Wang, Julong Lan, Xiaoqiang Xi, Ximian Fan, Yiming Jiang

“…Software defined networking updated data through distributing flow table to switches.But the installation of flow table had delay and may lead to wrong forwarding.An consistent routing policy based on ant algorithm was proposed.The inconsistent delay was introduced in routing parameter.The sequence of flow setup was adjusted through the controller,so as to avoid the inconsistency of the control logic in switches.Results show that,compared with Dijstra algorithm,when the inconsistency problem happens,the proposed policy has less actual delay and the packet lost rate and the wrong forwarding rate have been increasinglydecreased.…”

Movement-assisted data delivery for delay tolerant mobile sensor networks by Hui-jie LI, Jian PENG, Tang LIU

“…A novel data delivery method named movement-assisted adaptive data delivery (MAD) was proposed.The data cache nodes were deployed in the buffer and the base station moves in the buffer regularly.The data was forwarded to the nodes which likely moved to the buffer and had the higher remaining energy,and the base station collects data in the moving process.MAD contains two parts,data forwarding and queue management.The former makes the decision by the movement trend and the residual energy.The latter was based on the size of the survival time and the replication.Simulation results show that MAD had relatively higher delivery ratio and longer network lifetime.…”

Edge-first-based cooperative caching strategy in information centric networking by Jiang ZHI, Jun LI, Hai-bo WU, Yong-mao REN

“…In order to optimize the replica placement in information centric networking,an edge-first-based cooperative caching strategy (ECCS) was proposed.According to the strategy,cache decision was made during the interest forwarding stage.The decision result and statistic information would been forwarded to upstream routers step by step.Utilizing the information,upstream nodes could update their cache information table immediately to achieve cooperative caching.The experimental results indicate ECCS can achieve salient performance gain in terms of server load reduction ratio,average hop reduction ratio,average cache hit ratio,compared with current strategies.…”

“…Aiming at the problems of slow and faulty path migration caused by distributed deployment and asynchronous operation of data plane forwarding devices in software defined network, a fast loop-free path migration strategy was proposed.First, a fast loop detection algorithm based on node ranking was proposed.By comparing the position differences of adjacent nodes on the old and new paths of the flow, whether there was a forwarding loop in the path migration process and the location detection where the loop occurs could be quickly determined.Then, a greedy update mechanism based on node relaxation dependency was proposed.The fast loop detection algorithm was used to uncover the relaxation dependency between the common switches on the old and new paths, and the number of switches updated in each round of the migration process was ensured to be maximized.Simulation results show that the proposed strategy can effectively avoid migration loops and obtain the optimal update time overhead under different network states compared with existing migration schemes.…”
