Monitoring on smartphones and mobile devices presents several challenges, such as limited battery power and computing resources, but also provides some unique opportunities, particularly the ability to capture contextual data. Incorporating the context of the activities being monitored could improve performance modeling. Real-time monitoring could also be used to facilitate context-aware applications. In this paper, we introduce a configurable integrated monitoring solution for mobile devices. The monitoring service efficiently integrates multiple monitoring requests, and allows clients to monitor simple metrics or receive notification of custom defined events. [ABSTRACT FROM AUTHOR]

Abstract: QoS support for power-constrained wireless mesh networks (WMNs) poses a significant challenge. WMNs are increasingly used as multi-purpose networks, i.e., they serve multiple objectives and different applications simultaneously. As a consequence, a one-size-fits-all routing solution is difficult to achieve, particularly when the performance and QoS expectations of these applications differ. This work proposes Configurable Mesh Routing (CMR), a toolkit that supports the discovery and management of routes based on any combination of a number of supported QoS metrics. This enables network users to deploy customized routes that meet their unique needs. Our experiment demonstrates how CMR is able to balance the network-wide goal of energy efficiency and application-specific QoS requirements. [Copyright &y& Elsevier]

Abstract: Wireless multicast for multihop ad-hoc networks ensures that the same information is delivered efficiently to multiple recipients simultaneously. However, existing protocols ignore the real-time nature of many wireless applications such as real-time video and audio communications in mesh and ad-hoc networks. Further, devices in such networks are typically energy-constrained, i.e., multicast protocols have to trade off timeliness with energy efficiency. This paper presents RTMC, a real-time multicast protocol for wireless multihop networks that allows receivers to specify their individual real-time constraints and establishes multicast trees such that receivers’ deadlines are met and overall energy consumption in the network is reduced. Toward this end, RTMC relies on dynamically prioritized packet scheduling on forwarding nodes, prioritized channel access at the MAC layer, feedback control for latency management, tree adaptations to address mobility, dynamic subscriptions and unsubscriptions, and adaptations to address link breakages. Simulation results show that, compared to non-real-time multicast techniques, RTMC can provide user-specific latency management while reducing the energy consumption in the network.
