Data Collection in WSNs Using Mobile Element and Hierarchical Routing
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
the collection of data from large-scale wireless sensor networks (WSNs) is a challenging task and these two approaches can increase the efficiency: 1)By hierarchical routing based on node clustering and 2) by mobile elements (MEs). Since either method has benefits and drawbacks, this paper presents a combined approach, called nodedensity-based clustering and mobile collection, to combine the hierarchical routing and ME data collection in WSNs. A number of cluster heads (CHs) collect information from cluster members and then an ME visits these CHs to collect data. First, for a randomly deployed WSN, a new CH selection approach based on the node density is proposed. The benefit is that the nodes which are surrounded by more deployed nodes are more likely to be CHs. Thus, the efficiency of both ME data collection and intracluster routing is improved. Second, a lowcomplexity traveling track planning algorithm is designed for an ME to pass by all CHs Extensive simulations show that the proposed topic leads to not only remarkable performance improvement but also swap between the network energy saving and the data collection latency. Index Terms—Data collection, mobile element (ME), wireless sensor networks (WSNs), cluster head (CH).
