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 present the simulation results of the comparative investigation of the performance of the constrained flooding routing protocol (CF) based on different path loss exponents using PROWLER. Our simulation results indicate that the path loss exponent 4.10 increases the network lifetime for the CF routing protocol than the path loss exponent 3.0.
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...
There have been many routing protocols proposed for data dissemination to multiple mobile sinks in Wireless Sensor Networks (WSNs), and the protocols regard each sink as an individually distributed single entity without relationship of each other. Recently, mobile group entities have been introduced in WSNs. A number of mobile sinks move together in a group manner, and mobile sinks in the group stay...
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...
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...
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...
