Lately the use of wireless sensor networks for monitoring seismic events has increased; however, these networks depends on the previous acknowledge of the infrastructure and topology. This topology can’t be updated if any of the nodes is lost during a seismic event, in addition the orientation of the first seismic wave can’t be predicted; because of this, it is necessary to use a type of dynamic network...
Straightline routing v2 algorithm is one of the optimized proposed model to route the data packets efficiently in multi hop heterogeneous Wireless sensor networks. Due to the constraint of WSN in terms of topology, connectivity, a theory about Next hop graph is proposed. In this paper the advent of the next hop graph is generated by supplimenting the graph into the ring based super node structure...
In wireless sensor networks (WSN), clustering, a method of grouping sensor nodes, has numerous advantages. To ensure long-term operation of clustered WSN, two efficient routing protocols are proposed in this paper. The first is the Control Data Dissemination Protocol (CDDP) which forms a tree that connects all the nodes in the network, this tree will be used later to transfer control data to the base...
In the WSN(Wireless Sensor Networks, WSN), part of the node failure will affect the normal operation of the entire network. In this article, we design a self-healing algorithm of cellular-type WSN through improvements of Flooding algorithm based on the frequency and distance, combining with cellular structure. The algorithm can send the failure information of the node in time and quickly organizes...
In this paper, we investigate the use of explicit disjoint for the multipath routing to achieve cost-efficient operation of wireless sensor networks. The focus is on constructing completely disjointed multiple paths between the source of sensing stimulus and the destination of gathered sensor data. We propose simple schemes for multipath construction based on explicit multiple anchor nodes. For the...
Wireless sensor networks can be utilized as powerful tools in order to monitor and, eventually, control an environment. The routing protocols, for the WSN, must have self-configuration characteristics aimed at discovering which is the best way for transferring the information, with delivery assurance and with minimum energy consumption, among the nodes that compose the network. This article proposes...
Event detection and notification is a common task in a wireless sensor networks (WSN). Efficient data aggregation and minimization of energy consumption are the great research challenges in WSN. In WSN, aggregated event information is more important than individual event information for energy saving and reliability. Proximity queries or query approximation can be used to reduce the complexity of...
Wireless Sensor Networks (WSNs) use tiny, inexpensive sensor nodes with several distinguishing characteristics: they have very low processing power and radio ranges, permit very low energy consumption and perform limited and specific monitoring and sensing functions. However, its security becomes an issue because in WSNs, there is virtual communication by passing the data through sensor via internet...
In this paper, we propose to enhance a data-centric dissemination framework with geographic information and network-level caching in wireless sensor networks. The proposed framework enhances data-centric routing with three principal components: (1) publish/subscribe paradigm to coordinate sources and sinks; (2) geographic diffusion to mitigate unnecessary data forwarding; (3) network-level caching...
Summary form only given. A quorum system is formed by organizing nodes into subsets called quorums, where every two quorums intersect and no quorum includes another quorum. The quorum system reduces the access cost per operation, to balance the load, and to improve the system scalability. All of these properties make quorum systems particularly attractive for large-scale sensor applications involving...
There are a large number of papers on security in ad hoc networks, only a few consider sensor networks. And those works on WSN mainly discuss the problem about key management. The main purposes of this work are to establish a trust on the neighbor relation in WSN and propose a solution of achieving the goal. Our solution includes a mechanism to establish a trusted relation between all neighboring...
Different from traditional networks, wireless sensor networks (WSNs) are highly dependent on specific applications and are severely constrained by energy, storage capacity and computing power. To prolong the lifetime of the whole networks, energy awareness is an essential consideration when we design or analyze routing protocols. In this paper, we present a review of recent routing protocols in WSNs...
