Wireless sensor networks can accommodate multiple applications by using a multi-stack architecture in order to deliver a large number of QoS. Multi-stack architectures can be optimized by allowing packet exchanges between stacks. However, routing loops may appear because of these exchanges. In this paper, we highlight the problem of routing loops generated when the same packet is routed according...
This paper addresses how to leverage the spatial multiplexing function of MIMO links to improve wireless network throughput. Wireless interference modeling of a half-duplex MIMO node is presented, based on which, routing, spatial multiplexing and scheduling are jointly considered in one optimization model. A linear program-based algorithm is proposed for the joint optimization, and numerical simulation...
This paper proposes a Destination Information based Probabilistic (DIP) routing protocol for vehicular sensor networks (VSNs). In DIP, the destination information of a packet is used to determine candidate neighbors and the moving pattern of a vehicle is used to help select the next hop for forwarding data. The design goal of this protocol is to minimize the packet loss in the network and thus improve...
Location-based services provide (and maintain) location information used by geographic routing protocols. Routing and location service are widely related, but handled separately in usual studies about Vehicular Ad hoc Network (VANET). In this paper, we propose a hybrid approach, denoted mobility-Prediction-based Hybrid Routing and Hierarchical Location Service (PHRHLS), coupling a VANET routing protocol,...
An analytical approach to quantifying the routing overhead in wireless ad hoc networks is presented in this paper. We find that in addition to the traditional control overhead and sub-optimal routing overhead, the retransmissions of discarded packets due to buffer overflow in receiver nodes on a route will consume extra bandwidth, which increasing the routing overhead. In this paper, we focus on the...
