WSNs hold the promise of many new applications that require the network to handle traffic with different priority levels and QoS requirement in an energy efficient way while avoiding collisions and interference. In this paper, we investigate several aspects related to the application requirements and the network states and resources in order to provide multi-QoS routing protocol for WSNs. We propose...
Due to the increased use of sensor nodes in a variety of application fields, wireless sensor networks need to handle heterogeneous traffic with diverse priorities to achieve the required quality of service. In this paper, we address the cross layer quality of service-aware scheduling for wireless sensor network with respect to delay and reliability in an energy efficient way. A node disjoint multipath...
Quality of service guarantees in wireless sensor networks is difficult and more challenging due to the fact that the available resources of sensors and the various applications running over these networks have different constraints in their nature and requirements. In this paper we present a novel heuristic neighbor selection mechanism in WSNs that uses the geographic routing mechanism combined with...
With the increased application of wireless sensor networks (WSNs) to military and civilian environments, securing the data in the network has become a critical issue. The severe resource constraints of sensor nodes and the broadcast nature of the wireless links as well as the challenging deployment environments of wireless sensor networks pose challenges for the quality and security of data transmission...
Several routing protocols have been designed in the recent years to support different wireless sensor networks requirements. In this paper, we introduce a new on demand routing protocol, Reliable Fault-Tolerant Multipath (RFTM), to improve the reliability of data routing in wireless sensor networks. RFTM is a multi objective routing protocol that meets diverse application requirements by considering...
