Extend Wireless Network's Lifetime Based on Developing Gossiping Routing Algorithm

Prolong node's lifetime that is limited by its battery, as long as possible is an important factor during wireless sensor network designing. Several routing algorithm have been adopted to manage the energy strategy of WSNs. Multi-hoping is considered to be data transmission technique in WSNs, and Gossiping is one of well-defined multi-hopping as an epidemic routing algorithm. Gossip algorithm constructs its routing based on random selection of intermediate nodes, thus leads to its inefficiency. In this paper, three algorithms proposed for developing Gossip algorithm, DGossip, EN_Gossip and ENL_Gossip. Network lifetime improved by considering the information of nodes location, energy and their distance to the base station. The simulation executed in MATLAB, and the results of the proposed algorithms show that they are more efficient than LGossip and ELGossip and prolong the overall network lifetime. Keywords: Gossiping, epidemic routing algorithm, DGossip, Network life time, EN_Gossip, ENL_Gossip

Cluster based Energy-Efficient and Reliable Routing for Mobile Wireless Sensor Networks

The main problem of energy efficient reliable routing is that it doesn’t provide any back up mechanism for the failure of the nodes. The work of the paper major depends on the alternate path provided if the link got failure and to provide energy efficient path in between the network.it will reduce the time,cost and increase the efficiency and the data rate of the network. In wireless sensor networks, because of unreliable wireless media, host mobility and lack of infrastructure, providing secure communications is bit difficult in this type of network environment. In present work to ensure the security in unreliable wireless communication the cluster based topology technique is used, to obtain confidentiality and authentication of nodes hash function and MAC (Message Authentication Code) techniques are use

Fault-tolerant and QoS based Network Layer for Security Management

Wireless sensor networks have profound effects on many application fields like security management which need an immediate, fast and energy efficient route. In this paper, we define a fault-tolerant and QoS based network layer for security management of chemical products warehouse which can be classified as real-time and mission critical application. This application generate routine data packets and alert packets caused by unusual events which need a high reliability, short end to end delay and low packet loss rate constraints. After each node compute his hop count and build his neighbors table in the initialization phase, packets can be routed to the sink. We use FELGossiping protocol for routine data packets and node-disjoint multipath routing protocol for alert packets. Furthermore, we utilize the information gathering phase of FELGossiping to update the neighbors table and detect the failed nodes, and we adapt the network topology changes by rerun the initialization phase when chemical units were added or removed from the warehouse. Analysis shows that the network layer is energy efficient and can meet the QoS constraints of unusual events packets

Context-Aware Gossip-Based Protocol for Internet of Things Applications

This paper proposes a gossip-based protocol that utilises a multi-factor weighting function (MFWF) that takes several parameters into account: residual energy, Chebyshev distances to neighbouring nodes and the sink node, node density, and message priority. The effects of these parameters were examined to guide the customization of the weight function to effectively disseminate data to three types of IoT applications: critical, bandwidth-intensive, and energy-efficient applications. The performances of the three resulting MFWFs were assessed in comparison with the performances of the traditional gossiping protocol and the Fair Efficient Location-based Gossiping (FELGossiping) protocol in terms of end-to-end delay, network lifetime, rebroadcast nodes, and saved rebroadcasts. The experimental results demonstrated the proposed protocol’s ability to achieve a much shorter delay for critical IoT applications. For bandwidth-intensive IoT application, the proposed protocol was able to achieve a smaller percentage of rebroadcast nodes and an increased percentage of saved rebroadcasts, i.e., better bandwidth utilisation. The adapted MFWF for energy-efficient IoT application was able to improve the network lifetime compared to that of gossiping and FELGossiping. These results demonstrate the high level of flexibility of the proposed protocol with respect to network context and message priority.
