“…[1] evaluates a range of different opportunistic networks routing protocols: Epidemic, Prophet, MaxProp [2] and TTR [8] in disaster scenarios running by simulating mobility models. The authors argued that for varying number of nodes and data quantity, MaxProp achieves the best delivery performance while TTR has the lowest overhead ratio.…”

“…[4] and [5] showed that this trace highly partitioned, sparse and dynamic. We evaluate E 3 F performance against the state-ofthe-art emergency OppNet routing protocol [1] across multiple criteria such as message success ratio, delay, overhead and energy consumption. The contributions of this paper are multifold: we provide dramatically increased coverage by exploiting new energy polling algorithm, intelligent packet scheduling and adaptive forwarding mechanisms while keeping resource overhead low and supporting high success ratios for two types of traffic: ad hoc query and dissemination.…”

Abstract-This paper explores the problem of improving coverage and capacity of large-scale communication networks in disaster-struck areas. We propose a novel integrated dynamic cross-layer distributed energy aware emergency framework, E 3 F, that spans large geographical areas and variable time ranges. E 3 F enables adaptive storage, dynamic packet scheduling and utility driven forwarding that avoids congestion and energy depletion. Our extensive experiments with realistic traces show significantly improved energy efficiency and low overheads while maintaining high success ratios for both data dissemination and query answering.

“…In the light of direct dissemination techniques, Delay Tolerant Networks (DTN) [4] are a variant of classic MANETs based on the carry-store-and forward paradigm. In [8], several dissemination schemes for DTNs (PRoHET [27], MaxProp [28], and TTR [29]) were evaluated in disaster scenarios. According to the results, MaxProp is the best technique in terms of packet delivery ratio (PDR), and TTR in terms of energy consumption.…”

“…Another flaw is the higher power consumption of 3G technologies used in cellular networks to transfer data compared to the Local Area Networks (LANs) technologies like Wireless Fidelity (WiFi) or Personal Area Networks like Bluetooth. For these reasons, Wireless Mobile Ad Hoc Networks (MANETs) [1][2][3] [4] can be an appealing alternative to be used in disaster response scenarios [5][6] [7] [8]. MANETs can connect mobile devices through wireless links without the need for a fixed infrastructure.…”

decentralized communications quickly and using common devices like mobile phones. Broadcasting is the main mechanism used to disseminate information in all-to-all fashion in ad hoc networks. The objective of this paper is to optimize a broadcasting scheme based on similarity/dissimilarity coefficient designed for disaster response scenarios through a multi-objective optimization problem in which several performance metrics such as reachability, number of retransmissions and delay are optimized simultaneously.

Delay/disruption tolerant networks (DTNs) are potentially applicable in the challenged scenarios like post-disaster environments. In such networks, data forwarding generally relies on the mutual cooperation of the nodes. However, in reality, despite the availability of necessary resources for data forwarding, a node could misbehave by dropping messages received from other nodes with whom it has no strong social ties. Such a node is called a socially selfish node, which would cause a poor delivery ratio in the network. In this paper, we aim to address the problem of multicast data forwarding in the presence of such selfish nodes, by means of efficient relay selection in DTNs. First, we define a realistic reputation model, in contrast to existing models, to define the socially selfish/misbehaving nodes in the network. Further, a game-theoretic analysis is carried out that implies data forwarding cost is also an influential parameter in handling selfishness/misbehavior. Subsequently, the problem is formulated as a constrained optimization problem, which is NP hard. Therefore, a heuristic is proposed by combining the reputation of a node and the cost of message forwarding to appropriately identify relay nodes, thus improve the performance of the multicast message delivery in the network. We utilize a social metric, centrality to minimize the message forwarding cost in terms of the number of relay nodes. Finally, the comparative performance evaluation in ONE simulator with practical scenarios shows the superiority of the proposed scheme over the other prominent schemes.
