In Wireless Sensor Networks (WSNs), sensor nodes are power constrained and have restricted lifetime. This necessitates understanding how much long the network prevails its networking operations as it is first concern of mission critical applications. In recent years, to increase network life, proper uses of routing protocols have been proposed. Soft-computing (SC) technique highly addresses their...
Wireless Industrial Automation Networks may comprise large number of sensors and actuators which are densely deployed in various parts of an industry to monitor and control physical parameters like pressure, temperature, humidity, flow, level, density etc.by utilizing IEEE 802.15.4 standard. Typically, a sensor node consists of sensing subsystem for data acquisition, processing subsystem for data...
In Wireless Sensor Network (WSN), routing is a challenging task due to traffic and network size. To route the number of packets in WSN, the idea is to consider about Zone Routing Protocol (ZRP). The first hybrid routing protocol having proactive and reactive features was ZRP. Reconfigurable Wireless Networks has an ability to reconstruct its networks if network crash takes place and ZRP follow, highly...
In order to solve the problems in wireless sensor networks, such as node failure and losing of master key, a secure communication model based on secret sharing in wireless sensor networks is presented in this paper. In this model, with the secret sharing mechanism, the master key is divided into n parts which are distributed to the council nodes. Accordingly the council nodes can protect the master...
Multi-hop is widely used in wireless sensor networks to deliver packets; however, biased energy consumption rate (BECR) always happens when using this delivery method. BECR can cause energy hole and isolate some nodes, which would decrease the connectivity of the wireless sensor networks, and reduce nodes' sensor effectiveness and network lifetime. Hence, we propose a scheme named potential-based...
In this paper, we study a wireless sensor network (WSN) as a social network in which the embedded sensors are the main entities as opposed to human beings in a traditional social network. In wireless sensor networks, the nodes resemble individuals in a way that they communicate with their peers, sometimes selectively hiding some information, sometimes selectively exposing some other information, generating...
Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Most of the attention, however, has been given to the routing protocols. The paper presents a new clustering scheme named HCMC based on improved Monte-Carlo localization algorithm MCBR. We also exploit multi-hop scheme between clusters...
