Three Dimensional WSN is common in application areas such as space monitoring, cave monitoring, study of under water eco system and so on. Intrusion is a common type of attack in case of WSN. It spends lot of energy for the purpose of intrusion detection which in turn reduces the life time of the network. Energy efficiency is essential in this process. Therefore we derive an algorithm for energy efficient...
In Wireless Sensor Networks, key management is required to offer a secure communication between sensor nodes. Many key management mechanisms have been proposed while considering the characteristics of sensor nodes. Despite the advances of key management techniques, wireless sensor networks still have vulnerable point since sensor nodes have the communication restrictions such as an ultralight, a low...
The following topics are dealt with: mobile ad-hoc network; sensor network; data management; network management; routing; localization; power awareness; energy efficiency; performance evaluation; QoS; MAC; coding application; network security; network privacy; target tracking; and performance enhancement.
Automated animal monitoring with energy efficient wireless devices mounted on the animals can improve efficiency of farming industry and increase its profitability by decreasing reliance on human labor. We discuss the practical deployment of delay tolerant store and forward cattle monitoring architecture that provides data retention, detecting custom events, notification issuing, remote and in-situ...
The security of multimedia data in wireless ad hoc networks (WANet) is commonly provided by encryption, i.e., the mathematical process that transforms a plaintext message into unintelligible ciphertext. Nevertheless, the classical and modern ciphers have all been developed without taking into consideration the intrinsic characteristics of multimedia flows. Our approach aims to reduce the computational...
Protecting personal privacy and energy efficiency are two primary concerns for mobile ad hoc networks. However, no energy-efficient multicast algorithm designed for preserving anonymity has been proposed to date. At the same time, existing approaches cannot be applied to anonymous routing due to their incapability of preserving anonymity. To solve this critical issue, we propose an energy-efficient...
This paper describes the state of the art of secure ad hoc routing protocols and presents SEDYMO, a mechanism to secure a dynamic multihop ad hoc routing protocol. The proposed solution defeats internal and external attacks using a trustworthiness model based on a distributed certification authority. Digital signatures and hash chains are used to ensure the correctness of the protocol. The protocol...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper discusses the problem of achieving bandwidth and energy-efficient neighborhood group key distributions (NGKD) in tactical wireless sensor networks (TWSNs). We present new techniques that improve NGKD performance while also improving the resilience of TWSNs against attacks that combine node capture with message interception. This is accomplished without introducing additional communications...
