Due to the limitation of energy, the routing protocols of Wireless Sensor Network (WSN) must minimize energy consumption and thus extend the network lifetime. Low Energy Adaptive Clustering Hierarchy (LEACH) is the first classical hierarchical routing protocol in WSN. A timer is introduced while electing the optimal sensor node as cluster head. During data transmission, ...

MWSN is routing data from its source to the destination. When data has to transfer from source to destination it has to go through by various nodes which are considered as hops. When data pass from one hop to another its link deteriorate which cause the problem of handover. Nodes have to search for other ...

With increasing demands of Electronics products in the domain of the industrial & consumer application, it becomes necessary to come up with new ideas of electronic products. In the field of communication, present real-time communication audio transmission uses technologies like WiMAX, IEEE 802.11, 3G and Bluetooth. But audio-streaming through Bluetooth or radio waves have drawbacks ...

Wireless reprogramming for a wireless sensor network is the process of uploading new code or changing the functionality of existing code. For security reasons, every code update must be authenticated to prevent an adversary from installing malicious code in the network. All existing reprogramming protocols are based on the centralized approach in which only the ...

Security has become one of the major issues for data communication over wired and wireless networks. In Wireless Sensor Networks (WSNs), the hackers can inject false data via compromised nodes and can able to alter the original files. There are many chances to perform a Denial of Service (DoS) attack in WSNs. Initially send the ...

In this paper, a hybrid fuzzy techniques and genetic algorithms have been used simultaneously. That both of them used for routing with congestion control approaches. Here, used 4 inputs for fuzzy interfaces system. If there are a number of different routes, the genetic algorithm is used. GA is not to follow the shortest route, most ...

An IIDS mechanism has been proposed for identification of such attacks and alerting the normal sensor nodes for reduction of data loss rate. The simulation result shows that the vulnerability like sinkhole attacks on WSN drops all the transmitted packets across the leader. The proposed IIDS captures the sinkhole nodes with the minimum computation and ...

Delay-Tolerant Networking (DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Examples of such networks are those operating in mobile or extreme terrestrial environments, or planned networks in space. The behavioral characterization of malware is an effective alternative to pattern ...

Rapid advances in Wireless Sensor Networks (WSNs) indicate that they are becoming increasingly complex. Consequently users and applications are becoming more demanding. Due to unique characteristics of WSNs, like small dimensions and limited resources and capabilities, energy consumption is imposed as one of the key factors. WSNs are becoming the primary research field for many ...

In this paper, the authors present the review of the various existing and recently proposed location privacy preserving techniques in Wireless Sensor Networks (WSNs) against a local as well as global eavesdropper. Knowledge of the network topology in Local eavesdropper is limited while global eavesdropper can analyze the overall traffic pattern. Privacy preservation techniques are ...
