Advances in computing and communication capacityhave greatly widened theirscope of application.Ranging frommilitary scenarios, to environmental monitoring, vehicular networks or search and rescue operations, the ability to deploy a dynamic communication platform on demandis not far from becoming commonplace.The thesis proposes the CHOPIN routing protocolfor mobile ad-‐hoc networks (MANET). The implementation is inspired by OLSR and was developed in response to the requirements of Human and robotic cooperation in search and rescue scenarios(Project CHOPIN). Current operational guidelines follow a centralized approach, where a Command Center (CC) coordinates activities on the field.Cooperative mapping (group communication), hazardous materials detection, victim localization and landmarks(communication towards the CC)are possible contributions from robotic agents, effectively reducing risk to human lives and allowing for distributed operation.Tests where performed for comparison between the proposed protocoland OLSR, with positive results.Through the use of a flooding optimization technique, MultiPointRelaying (MPR), OLSR operation results in less control overhead. On the other hand, CHOPIN maintains lesser state information,resulting in a lower memory footprint.In regard to some relevant metrics like convergence time,latency and throughput, the protocols behave onpar, with CHOPIN slightly on the lead||Description:||Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra||URI:||http://hdl.handle.net/10316/35602||Rights:||closedAccess|
