Resource Aware Routing in Heterogeneous Opportunistic Networks

Self-Interference Aware Opportunistic Routing Metric in Wireless Mesh Networks

In this paper, we present a novel routing metric named SIOR which is designed for opportunistic routing in single-rate wireless mesh networks. Most of the existing routing metrics either assume too pessimistically that all links within the network interfere with each other or do not consider intra-flow interference at all. In fact, any flow which has its destination node at least two hops away ...

A Socially Aware Routing Protocol in Mobile Opportunistic Networks

—Routing is one of the difficult issues in mobile opportunistic networks, due to the lack of global knowledge and sporadic links. Related works use a greedy strategy to forward packets, i.e., they select relays with higher/bigger quality metrics. In this paper, we study the Opportunistic Routing Protocols (ORPs) from the perspective of social network analysis. Specifically, we discuss the impa...

GAR: Group aware cooperative routing protocol for resource-constraint opportunistic networks

Routing in Opportunistic Networks

In Opportunistic Networks (OppNets), mobile devices transmit messages by exploiting the direct contacts, without the need of an end-to-end infrastructure. Disconnections of nodes and high churn rates are normal features of opportunistic networks. Hence, routing is one of the main challenges in this environment. In this article, we provide a survey of the main routing approaches in OppNets and c...

A social-aware routing protocol for opportunistic networks

This work proposes the Cultural Greedy Ant (CGrAnt) protocol to solve the problem of data delivery in opportunistic and intermittently connected networks referred to as Delay Tolerant Networks (DTNs). CGrAnt is a hybrid Swarm Intelligence-based forwarding protocol designed to address the dynamic and complex environment of DTNs. CGrAnt is based on: (1) Cultural Algorithms (CA) and Ant Colony Opt...
