Wireless sensor network are constituted by a large number of tiny size sensors and distributed randomly for gathering information. These types of networks have remarkable applications and demand worldwide. The wireless sensor network has been suffered with variety of attacks because of its design and deployment nature. The previous traditional approaches including cryptography, authentication c...

Wireless Sensor Network (WSN) diverts the attention of the research community as it is easy to deploy, selfmaintained and does not require predefine infrastructure. These networks are commonly used to broadcast multimedia data from source to destination. However, this kind of data transmission has some challenges, i.e. power and bandwidth limitation with small delay. Art of work mainly focus on...

Wireless routing is an area of research which is being focused mainly for congestion avoidance and security. Various routing protocols and techniques are being included in wireless network and making it an area for further research. The need is increasing more due to invention and adaption of wireless communication devices for wireless communication. This work is focusing on security over multi...

A sensor network is nothing but the collection of number of wireless mobile nodes. Each node route the packet as well as forward the packet until the destination. Many routing protocol have been developed in mobile networks. Protocol selection is the main purpose of the wireless network and selected protocol must be best in all aspects of the mobile network. In this paper, simulation performanc...

Several data forwarding and clustering techniques have been proposed to improve Underwater Wireless Sensor Networks (UWSNs) performance, but void communications, packet collisions, energy efficiency remain unresolved. We introduce a novel routing solution for QoS-efficient transmission from the underwater sensor node surface sink using Swarm Intelligence (SI). The protocol Energy Optimization R...

Mobile ad hoc network consists of mobile node where no infrastructure exists. If a node wants to communicate with other node, it needs to obtain its location to forward the data packets. Due to high mobility nature, communication will get degraded because of less packet delivery rate. In previous location aware routing protocols, multipath routing is not deployed with location updation. In this...

Mobile Ad hoc Network (MANET) is a group of wireless node, which rapidly moves, changes and forms a network without need of centralized controlling entity [1]. The entire nodes in MANET intercommunicate with other node which stays in its relative frequency range. Each node in MANET works as router, so each node forward packet to neighbor node until packet it reaches to destination. There are ma...

.Due to limited resources of individual senor nodes, there is usually a trade-off between energy spending for packets transmissions and the appropriate level of reliability. Since link failures and packet losses are unavoidable, sensor networks may tolerate a certain level of reliability without significantly affecting packets delivery performance and data aggregation accuracy in favor of effic...

In this paper we develop a Directional Antenna Multi-path Location Aided Routing (DA-MLAR) scheme with On Demand Transmission Power (ODTP) support. The routing approach is based on multiple objectives. DAMLAR is a reactive routing protocol that minimizes the protocol overhead of other reactive routing protocols. DAMLAR also improves the packet delivery ratio and end-toend delay. The targeted ap...
