The MEOW model-based design of an energy-optimized protocol stack addresses energy-aware functional design, optimization, simulation and code generation for WSNs. The goal is to satisfy functional and performance requirements, while maximizing battery lifetime. MEOW has been developed using the Matlab and Stateflow tools, which can be used in a model-based design environment to provide opportunities...
Recent developments in the field of transmission line monitoring system have led to a renewed interest in wireless sensor networks, which is characterized by the strong real time, high reliability, adaptability, load balancing and so on. However, the bottleneck problem of network transmission which is likely to occur around the sink node must be taken into account. This paper proposes a new cross-layer...
In wireless sensor networks with mobile sinks, it is a challenge to design reasonable data dissemination protocols to realize reliable, real-time and efficient data transmission from multiple sources to multiple sinks. Recently, many protocols such as TTDD, GHT and LBDD are proposed to solve this problem. However, most of them depend on the whole network topology information to optimize the data dissemination...
Delay-Tolerant/Disruption-Tolerant Networks (DTNs) have been proposed to cope with the challenges of communication in some extreme or special environments. Due to the uncertainty of node mobility, application traffic demand and other factors, it is difficult to provide performance guarantee for a DTN where all nodes may move arbitrarily. With controlled mobility, message ferries can be utilized to...
Data aggregation is an important issue in wireless sensor networks which gathers and routes information through a multi-hop network and processes data at intermediate nodes. This paper considers how to construct data aggregation tree in wireless sensor network where there are several source nodes and a single sink. Ant Colony Optimization algorithm is an effective distributed approach. It has been...
At present, the field of wireless sensor networks (WSNs) is an important and challenging research area. Advancements in sensor networks enable a wide range of environmental monitoring and object tracking applications. Moreover, multihop routing in WSN is interrupt by new nodes constantly entering/leaving the system. Therefore, biologically inspired algorithms are reviewed and enhanced to tackle problems...
We consider problems where multiple agents cooperate to control their individual state so as to optimize a common objective while communicating with each other to exchange state information. Since communication costs can be significant, we seek conditions under which communication of state information among nodes can be minimized while still ensuring that the optimization process converges. In prior...
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...
This paper develops Ant Colony optimization (ACO) algorithm and applies it to energy control and congestion control on wireless sensor network route. The pheromone and the energy of the node are combined to affect the pheromone consent ration in optimization path, which can avoid network congestion and fast consume of energy of individual node. Then it can prolong the lifecycle of the whole network...
As wireless sensor networks (WSNs) increasingly attract more attention, new ideas for specific applications are continually being developed, many of which involve the energy consumption of nodes. However, not much has been done to optimize the quality of services (QoS) of WSNs. Many applications like target tracking require some QoS guarantees. Besides, certain factors limit the ability of multi-hop...
