GAAP: um protocolo de alocação de endereços para redes ad hoc móveis em cenários de emergência

Abstract

In emergency scenarios, such as in natural disasters, technological or manmade, search and rescue teams in the affected region may use solutions for mobile ad hoc networks (Mobile Ad hoc Networks - MANETs) to address any lack of network infrastructure communication. Emergency networks are those built on disaster scenarios and have properties such as robust and resilient communication, not necessarily have some communication infrastructure and mainly offer not only data communication but also voice. Thus, in case of lack of communication infrastructure, a MANET can act as an emergency network. For communication between nodes in a MANET can be performed, it is necessary that each node is configured with unique address. Due to the ability of nodes self-organize, by creating temporary and arbitrary topologies, address allocation should be done automatically. Many papers have appeared dealing with the allocation of addresses in MANETs, but most solutions presents a number of limitations related mainly to the limited applicability in scenarios and introduction of high control traffic on the network. In this context, this paper presents a new solution for address allocation that assigns unique addresses to nodes in emergency networks. Results showed that the proposed solution is efficient in critical scenarios in comparison with other protocols examined, with low latency to obtain an address and reduced control traffic on the network reduced.
