In a Wireless Sensor Network (WSN), there are a large number of nodes whose power supply and computational capability are limited. The nodes in a wireless sensor network can be fixed or move randomly. Thus in these networks, to forward a data packet from one node to another needs to use specific strategies with very different characteristics. Accordingly the data forwarding strategy among nodes plays...
To ensure the security of the data forwarding and requirement of QoS(Quality of Services) in wireless sensor networks, we propose an ant colony optimization-based trustful routing algorithm. The objective function includes the key factors, such as the time delay, the bandwidth and the energy consumption of the link from the source to the destination. Also, in order to optimize the path selection,...
Recently there has been an exponential rise in the use of Wireless Sensor Networks (WSNs) in various applications. While WSNs have been primarily used as independent networks, researchers are now looking into ways of integrating them with other existing networks. One such network is the satellite network which provides a reliable communication backbone to remote areas that lack appropriate terrestrial...
In this work, we propose a new framework able to ensure the Quality-of-Services (QoS) with different security levels in Wireless Sensor Networks (WSNs). We propose a new model based on the PID (Proportional Integral Derivative) controller in order to dynamically select the security level adapted to QoS requirement while considering the energy consumption. The stability parameters in terms of security...
