Μελέτη ζητημάτων κόστους - οφέλους και βελτιστοποίησης υπό την παρουσία περιορισμών σε δίκτυα αισθητήρων
This dissertation addresses the cost issues that exist in wireless sensor networks under certain restrictions and presents ways to optimize the performance of networks. Specifically, presents the communication protocols and compares with each other to clear up the advantages and disadvantages of each protocol. The most important issue that arises in sensor networks is energy consumption which is derived from the low energy range of sensor nodes. So, most comparisons between protocols basically revolve around energy consumption of nodes and the lifetime of the network. Finally we have implemented in C language the LEACH protocol and we plotted the results with the help of MATLAB. We compared LEACH with the direct communication protocol to the issue of energy consumption.
