    Modified Elastic Routing to support Sink Mobility Characteristics in Wireless Sensor Networks
    (CERIST, 2015-04-12) Benkhelifa, Imane; Belmouloud, Nassim; Moussaoui, Tabia
    This paper presents improvements for the geographic routing protocol Elastic so to support the different sink mobility characteristics. We have proposed a strategy to support multiple mobile sinks; tested Elastic under high speeds of the mobile sink; proposed two strategies in case of the sink temporary absence and finally proposed to predict the sink location by the source node and then by all the nodes. Simulation results show that our propositions improve much the delivery ratio and reduce the delivery delay.

    Performance Analysis of Sinks Mobility in Geographic Routing for Wireless Sensor Networks
    (CERIST, 2015-04-12) Benkhelifa, Imane; Belmouloud, Nassim; Tabia, Yasmina; Moussaoui, Samira
    This paper presents a performance analysis of sinks mobility in geographic routing based on performance evaluation of two geographic routing protocols namely GPSR with static sinks and Elastic with mobile sinks. Among the scenarios, we observe also the impact of using multi-mobile-sinks, in addition to the effect of mobility model through changing the sink’s trajectory and speed. We analyze the performance results by calculating the delivery ratio of the transmitted packets, as well as the average delay of transmission and the number of hops necessary to transmit successfully a packet from the source to the sink. We show that mobile sinks can play a major role in prolonging the network lifetime and the efficiency of a geographic routing protocol.
