Routing in WSN

A wireless sensor network (WSN) is a collection of wirelessly connected multifunction sensor devices (referred to as wireless sensor nodes) in an area that requires sensing. In this paper, we synthesize the classification and arrangement of energy-efficient and SRPs, as well as provide a method to calculate attack probability (AP) for secure routing in WSN.

This study suggests an optimal coverage model aimed at the optimal deployment of Wireless sensor networks (WSN) based on improving the artificial bee colony (ABC) algorithm. The distance between the sensor nodes is regulated reasonably by implementing quasi-gravitation and quasi-coulomb power. Also, with a low regional repetition rate, the ABC algorithm can achieve fast optimization. Besides, to minimize node energy consumption, the sensing radius of WSN nodes is dynamically modified.

Topology issues should receive more and more consideration in Wireless Sensor Networks (WSN). While the supplied underlying network topology typically optimizes WSN applications, another inclination is observed to optimize WSN employing topology control. In the current ten years, wireless sensor network technology has speedy development. After a concise prologue of the wireless sensor network, some main protocols of WSN are provided. Then the comparison is made between the various protocols with advantages and disadvantages.

In this paper, we propose a novel solution combining an event driven routing protocol, dynamic delivering scheme, and energy aware to support QoS requirements for three event types in multiple event WSN. Simulation results show that, the proposed solution significantly reduces packet loss rate for high reliability requirement events and extends the network lifetime of multievent WSN.

There are many routing protocols proposed for WSNs to deal with challenges such as energy depletion and latency of data transmission from nodes to base station. Recently, researchers have focused on Chain-based protocols. CCBRP (Chain-Chain Based Routing Protocol) tries to decrease both energy consumption and latency time, but it has some challenges such as randomness in choosing of chain leaders and not supporting of any fault tolerant mechanism. Due to energy depletion and mobility of nodes, nodes failure is unavoidable in WSNs.

To accomplish this, a reliable transportmechanismis required in addition to robust modulation and media access, link error control and fault tolerant routing. The functionalities and design of a suitable transport solution for WSN are the main issues addressed in this paper. The need for a transport layer for data delivery in WSN was questioned in a recent work [12] under the premise that data flows from source to sink are generally loss tolerant.

Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed over a wide geographical area, indoor or outdoor

The other routing protocols have been proposed in WSN to improve QoS other restrictions such as the delay. The problem here is that the complexity of the routing protocol significantly increased with integration of more than one QoS parameter. Indeed, define a QoS route meets two or more countries not limited correlation (eg, delay, and bandwidth) is an NP- complete problem (Mellouk et al, 2007), because many limitations optimal path problem can not be solved in polynomial time.
