Wireless Multimedia Sensor Networks(WMSNs) have the characteristics of limited resources, variable channel capacities and high data redundancy, which pose great challenges to the QoS routing of WMSNs. Addressing these issues, an Ant Colony Optimization-based Load Balancing Routing Algorithm (ACOLBR) is proposed. Firstly, the intra-cluster routing is built by the minimum spanning tree. And then the...
We target an interesting problem of simultaneous optimization of lifetime and source-to-sink delay in wireless sensor networks, and present a fuzzy multiobjective online routing algorithm. For a routing request, the proposed routing algorithm finds a path that offers a good balance between the two routing objectives, namely maximizing the network lifetime and minimizing the source-to-sink delay. Fuzzy...
Energy balance is an important performance index in the design of routing algorithm for wireless sensor networks. A swarm intelligence optimization based routing algorithm for wireless sensor networks is proposed, whose kernel idea is taking less hop numbers into consideration and choosing the nodes with less pheromone as next hop to avoid some nodespsila prematurely exhausting their energy because...
