In wireless networks, a watchdog mechanism can be a part of the security architecture used to identify nodes that fail to forward the packets they agree to forward. In this paper, we propose two protocols to address the ambiguous collision limitation of watchdogs. The Watchdog Alert (WA) and Watchdog Confirmation (WC) protocols are variants of the Carrier Sense Multiple Access with Collision Avoidance Protocol (CSMA/CA). We analyse the trade-offs between throughput and watchdog success… 

A novel secure and multipath routing algorithm in Wireless Sensor Networks

The concept of k-connectivity is extended to k-x-Connectivity where x is the value of threshold representing the maximal number of nodes shared between any two paths in the set of the k established paths.

A new hierarchical and scalable group key exchange protocol with XOR operation

This paper proposes a GKE protocol originated from a two-participant key exchange protocol and proves that the protocol is secure, representing the protocol as processes in the spi calculus, and state their security properties as queries in ProVerif, an automatic analyser based onSpi calculus.

This work introduces an approach that can be applied to calculate the trust in a dynamic way, and also protect the message against modification, without significantly increasing the overheads.

Threshold Based Multipath Routing Algorithm in Mobile Adhoc and Sensor Networks

While communicating nodes in Mobile Adhoc and Sensor Networks (MASNets), need to use multipath routing algorithms to tolerate nodes and links failures, it becomes interesting to let them specify to

Study on Data Fusion Techniques in Wireless Sensor Networks

A survey is presented in this article studying on the data fusion techniques in WSNs from the aspects of cluster based schemes, chain based schemes to statistics based schemes and their advantages and disadvantages.

A novel hybrid incentive mechanism for node cooperation in mobile cyber-physical systems

It is found that when the percentage of selfish nodes is not above 60, RCM can improve the network performance while the necessary payment is lower, and this study presents a novel hybrid incentive mechanism with reputation-formed payment risk, called reputation-based credit mechanism (RCM).

Mitigating routing misbehavior in mobile ad hoc networks

Two techniques that improve throughput in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so are described, using a watchdog that identifies misbehaving nodes and a pathrater that helps routing protocols avoid these nodes.

PAMAS—power aware multi-access protocol with signalling for ad hoc networks

A new multiaccess protocol based on the original MACA protocol with the adition of a separate signalling channel that conserves battery power at nodes by intelligently powering off nodes that are not actively transmitting or receiving packets.

Key Management in Wireless Sensor Networks

Probabilistic, deterministic and hybrid key management solutions are presented, and a set of metrics are determined to quantify their security properties and resource usage such as processing, storage and communication overheads.

Performance analysis of the CONFIDANT protocol

It is shown that a network with CONFIDANT and up to 60% of misbehaving nodes behaves almost as well as a benign network, in sharp contrast to a defenseless network.

A Power Control MAC Protocol for Ad hoc Networks

A novel power controlled MAC protocol based on SNR in mobile Ad hoc networks is presented and simulation results demonstrate that compared to the IEEE 802.11 MAC protocol, the proposed protocol can decrease the power consumption greatly, and improve the energy utilization of mobile terminals while maintaining the throughput performance.

It is observed that in dense sensor networks, overhearing costs constitute a significant fraction of the total energy cost and that computing the minimum spanning tree on the augmented cost metric results in energy savings, especially in networks with non-uniform spatial node distribution.
