Efficient and reliable routing protocol is one of the key technologies in wireless sensor networks, and it has been concerned by a lot of researchers. In light of the random selection of cluster head in low energy adaptive clustering hierarchy protocol algorithm, the residual energy of nodes, node location and node density are not considered. Through theoretical deduction and mathematical calculation,...
ZACA-EEC (Zigbee Ant Colony Algorithm Energy Efficient Cluster) routing protocol is proposed to replace AODV in Zigbee with the aim of increasing reliability for mine equipment monitoring in this paper, which can prolong the lifetime of network remarkably. Taking hydraulic support as an example, the distribution of monitoring nodes can be simplified as chain hierarchy topology, then Free-space model...
Rumor routing is a routing protocol based on query for wireless sensor networks, which selects next hop randomly during establishing path and the path may not be optimal and may be loop. So this paper puts forward a novel rumor routing (NRR), which bases on ant colony optimization and can resolve the loop route that established by rumor routing, and has good convergence, comparing to rumor routing,...
A Wireless Sensor Network (WSN) is typically depicted as a distributed resource constrained platform for supporting novel pervasive applications. A possible approach is to develop applications over WSNs by resorting to mobile agent frameworks that are aimed to minimize resource costs and memory allocation. In this context, network topology is a major issue to be considered for resource optimization:...
Energy efficient multicast routing is one of the fundamental problems in wireless sensor networks (WSNs). Previous work has shown that when the goal is to find multicast trees with minimum transmission cost, the problem becomes NP-complete. In this work, we present a heuristic distributed minimum transmission multicast routing protocol (MTMRP) for WSNs. By introducing the biased backoff scheme and...
At present most of the WSNs routing protocol only have a single research objective. The overall network performance lacks of multi-objective inspection and evaluation. The basic task of multi-objective routing is to find a route in the network which has sufficient resources to optimize some network parameters and satisfy multiple constrains. A multi-objective model, constrained of bandwidth, is put...
This paper deals with the model of Adaptive multi-hop routing algorithm for Wireless Sensor Network (WSN) and its results are presented. Certain parameters like energy level, delay and velocity are considered. These decisions will come up with the optimal and organized route for WSN. In addition, the stated algorithm is enhanced with the multipath capability to avoid congestion state in WSN. Eventually,...
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...
Energy conversation is a critical problem in wireless sensor networks (WSNs) so that the energy consumption must be minimized while satisfying application requirements. The energy efficiency can be supported across all layers of the protocol stack. In this paper, we propose and analyze a cross-layer energy efficiency model, which takes routing layer, MAC layer, data link layer, hardware circuitry,...
One of the fundamental operations in sensor networks is convergecast which refers to the communication pattern in which data is collected from a set of sensor nodes and forwarded to a common end-point gateway, namely sink node, in the network. In case of multiple sinks within the network, the total load of the network has to be balanced among these sinks to minimize the problem of packet loss in the...
In wireless sensor networks (WSNs), message security is an important concern. The protection of integrity and confidentiality of information and the protection from unauthorized access are important issues. However, due to factors such as resource limitations, absence of centralized access points, open wireless medium and small size of the sensor nodes, the implementation of security in WSNs is a...
