Simulation system is a real time system, in which data communication mechanism is the key point to assure the correctness of test data and real time data transferring. This paper will start from the architecture of simulation test system, and then build a data communication model according to data type and transferring requirements of the simulation test system. We present a test data communication...
In this paper we study the information spreading behavior of selected, mobility models combined with epidemic algorithms and the dynamic routing efficiency of gossip based routing algorithms on ad-hoc networks. Epidemic algorithms follow a paradigm of nature where simple rules dictate the spread of information by having a local view of the environment. In our work, three models of mobility, Random...
An energy-efficient data gathering protocol called E2DGP that takes advantage of spatial and temporal correlation of sampling data for WSNs is proposed in this paper. E2DGP includes a clustering method of balancing energy consumption, a data prediction transmission strategy and an energy-aware multihop routing algorithm. In clustering process phase, the initial probability of node for cluster head...
Data aggregation is an essential paradigm for energy efficient routing in energy constraint wireless sensor networks (WSN). Data aggregation in WSN can be treated as searching for the Minimum Steiner Tree (MST) including source nodes and sink node. In this paper, we propose a Data-aggregation Algorithm based on Adaptive Ant Colony System (AACS) algorithm. In this algorithm, Directed Diffusion (DD)...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
