This paper introduces a novel approach to transport messages between a backbone network and a device network (SAN) in a seamless way, even when these networks use incompatible protocols or technologies. The paper shows how to leverage a general purpose distributed object oriented middleware to encapsulate and send messages as object invocations. Devices and routers are modeled as standard distributed...
In WSNs and tiny cooperating wireless robots, unit and communication faults (permanent or transient), energy availability for the units and environmental changes may modify the communication network topology over time. Traditional hierarchical routing algorithms combine adaptability to changing environments with energy-aware aspects. In this paper we propose a k-level hierarchical extension to low-power...
The quality-of-service (QoS) routing in a wireless sensor network is difficult because the network topology may change constantly, and the available state information for routing is inherently imprecise. In this paper, we propose a distributed QoS routing that selects a network path with sufficient resources to satisfy a certain delay requirement in a dynamic environment. Multiple paths are searched...
Optimum theorems for combining QoS metrics to reduce computation time in nodes (routers) is proposed based on fundamental theorems on QoS metrics. The proposed theorems unify selection of metrics and provide the methods for reducing overheads at the nodes due to performance metrics. Specified metrics are used to define QoS target, benefit, link and route availability functions. It is shown that for...
