An Efficient Approach to Minimize Data Collection Delay in Wireless Sensor Networks
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 4
Abstract
Data assortment latency might become higher attributable to the comparatively slow travel speed of mobile components . Thus , the planning of mobile components , i.e. , however they traverse through the sensing field and once they collect knowledge from that device , is of final importance and has attracted increasing attention from the analysis community. developed because the bagman drawback with neighborhoods (TSPN) and attributable to its NP-hardness , thus far solely approximation and heuristic algorithms have appeared within the literature , however the previous solely have theoretical worth currently attributable to their giant approximation factors. during this paper , following a progressive optimisation approach , we tend to 1st proposes/proposed a combine-skip-substitute (CSS) theme , that is shown to be able to acquire answers at intervals atiny low vary of the edge of the best solution. we tend to then take the realistic multirate options of wireless communications under consideration , that are neglected by most existing work , to additional cut back the info assortment latency with the multirate CSS (MR-CSS) theme . Besides the correctness proof and performance analysis of the projected schemes , we tend to additionally show their potency and potentials for additional extensions through intensive simulation . Finally assortment jobs requested by cluster heads instead device nodes to balance energy usage.
