Applicability of Structured and Unstructured Communication Techniques in Emergency Environment

Abstract

Peer-to-Peer (P2P) from of networking is among the best communication strategy for any emergency scenario. An important characteristic of such network deployed for handling emergency communication is the dynamicity and heterogeneity of the nodes. Due to this behaviour, the number of nodes joining and leaving the topology would be rapid resulting in expensive network maintenance. The communication requirement for such networks suits a dynamic approach for handling as per the changing network topology for a reliable and efficient solution. For applicability of different P2P communication types such as structured, unstructured, cluster and hierarchical P2P are analysed. Different emergency scenario is created in OMNeT++ simulator and analysed on parameters like Packet drop ratio, Throughput and End-to-End delay resulting to the outcome that no single P2P communication strategy is perfect.
