Performance trade-offs of an energy-aware version of a location-based reactive multi-hop protocol, namely the Greedy Perimeter Stateless Routing, are investigated, by means of extensive dynamic simulations of a low-data rate location/tracking system. As those systems usually implement the simplest aloha MAC, it is necessary to keep at the minimum the updating beacon traffic. Balancing this constraint with the opposite necessity of the proposed routing of using up-to-date information about neighbor nodes, we show that a maximum performance exists for an optimal value of beacon repetition rate, that varies with the nodes’ mobility degree. We also assess the effectiveness of the use of positions’ prediction models.

Abstract

Performance trade-offs of an energy-aware version of a location-based reactive multi-hop protocol, namely the Greedy Perimeter Stateless Routing, are investigated, by means of extensive dynamic simulations of a low-data rate location/tracking system. As those systems usually implement the simplest aloha MAC, it is necessary to keep at the minimum the updating beacon traffic. Balancing this constraint with the opposite necessity of the proposed routing of using up-to-date information about neighbor nodes, we show that a maximum performance exists for an optimal value of beacon repetition rate, that varies with the nodes’ mobility degree. We also assess the effectiveness of the use of positions’ prediction models.
