[Background] Mountain torrent disasters are one of the deadliest weather-related natural in world, often causing extremely serious economic and property losses casualties; recent years, due to heavy rainfall complex geological geomorphological conditions, mountain have occurred frequently Gansu Province. An effective rainfall-runoff model is key prevent them. There still many problems about how...

Wireless Sensor Networks (WSNs) are designed for many monitoring and surveillance tasks. A typical scenario category is the use of WSNs for disaster detection in environmental scenarios. In disasters such as forest fires, volcano outbreaks or flood disasters, the monitored events have the potential to destroy the sensor devices themselves. This has implications for the network lifetime, perform...

This paper presents on-demand routing scalability improvements achieved using a “passive” clustering. Any on demand routing typically requires some form of flooding. Clustering can dramatically reduce transmission overhead during flooding. In fact, by using clustering, we restrict the set of forwarding nodes during flood search and thus reduce the energy cost and traffic overhead of routing in ...

In MANET, breaking of communication connection is exceptionally less, as nodes are allowed to move to any place. Location-Aided Routing (LAR) is an on demand routing protocol that minimize the conjunction and overhead of route discovery by utilizing location information of mobile nodes obtained using Global Positioning System (GPS). Along with that consumption of battery power by any node over ...

Routing in a wireless mesh network is a heterogeneous interoperability problem. First, it is possible that some users may disable the relaying functions of their mobile devices in order to save the computing power and battery charge. This will results in heterogeneous relaying capabilities. Second, due to the absence of standard layer-3 ad-hoc routing protocols, various devices may employ diffe...

Wireless Sensor Networks (WSNs) have a broad application range in the area of monitoring and surveillance tasks. Among these tasks, disaster detection or prevention in environmental scenarios is one typical application for WSN. Disasters may for example be forest fires, volcano outbreaks or flood disasters. Here, the monitored events have the potential to destroy the sensor devices themselves. ...

Query Localization is a recently proposed extension for On-Demand Routing Protocols which reduces overheads of route discovery by restricting the query flood to the vicinity of previously discovered routes. In order to effectively define the request zone in Query Localization, the past connectivity information needs to be utilized to the fullest extent. In this paper we propose a swarm intellig...
