Design of energy efficient underwater wireless sensor networks (UWSNs) routing protocol to prolong network lifetime is a challenging task because of limited battery life of sensor nodes. In this paper, we propose mobile energy efficient square routing protocol (MEES) to balance energy consumption of nodes in the network. Two mobile sinks are deployed at the farthest distance from each other. In order...
Mobility management in Mobile Wireless Sensor Networks (MWSNs) is a complex problem that must be taken into account. In MWSN, nodes move in and out of the network randomly. Hence, a path formed between two distant nodes is highly susceptible to changes due to unpredictable node movement. Also, due to the limited resources in WSN, the paths used for data transmission must be tested for the link quality...
Location based protocols use the information of node's position to route the data. Routing the data in this case does not mean choosing the shortest path. It means choosing the available path based on the location information, this is one of the reasons that these protocols may fail the routing task in mobile Ad-hoc Networks (MANET) where the mobility of the nodes and the dynamic topology makes the...
Mobile sinks are proposed as a possible solution to the hotspot problem, which leads to the early death of the nodes close to the sink, due to the concentration of data traffic towards the sinks. However, the route updates employed by the source nodes to determine the position of the sinks introduce an overhead in terms of data reporting delays and energy consumptions. On the other hand, decreased...
In this paper, we present a novel bio-inspired trusted routing framework (B-iTRF) which composed of trust mechanism and routing strategy. For trust mechanism, B-iTRF monitors neighbors' behavior in real time and then assesses neighbors' trust value based on the priori knowledge. For routing strategy, each node finds routes to the Sink based on ant colony optimization. In the process of path finding,...
The routing algorithm is one of key researches of interconnection networks and wireless sensor networks (WSN) design. WSNs are application specific, hence lots of attention has been given to routing protocol. Since the life time of sensor nodes depend on available power, therefore in order to prolong the age of sensor nodes, it is necessary to design efficient routing protocols. The routing protocols...
In wireless sensor network, the nodes forward large amount of data to the sink which causes several problems like energy and data losses. This work focus on efficient data gathering and aggregation with limited energy consumption among sensor nodes for increasing the network lifetime. This study introduces the RPEVI (Reference Point Imparting Mechanism) for efficient data gathering and bounded data...
This paper presents a new data transmission protocol in Delay Tolerant Mobile Wireless Sensor Networks, which divides the data transmission process into two phases: data reception phase and data forwarding phase, mainly fulfilling through analyzing the state of mobile nodes and using Hand up mechanism. Simulation result shows that, through the implementation of two phases, we can obtain a higher message...
This paper presents a design of routing algorithm for mobile agent in the wireless sensor networks which is called MA-SWR. It introduces a weight metric and each node derives its weight value dynamically from its current position. In MA-SWR, by comparing the weights values, mobile agents can determine their own routs. MA-SWR can be applied when topological information changes such as in a network...
Most routing solutions for wireless sensor networks utilize static sinks to collect data from the entire network. This approach results in high traffic load at nodes located near the sink. These sensor nodes will be more requested than other nodes in the network, resulting in longer delays and packet losses. In this paper, we propose a mobile data collector strategy in order to alleviate the high...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
