We consider the problem of merging two sorted arrays and on an exclusive read, exclusive write parallel random access machine (EREW PRAM, see [8] for a definition). Our approach consists of identifying elements in and which would have appropriate rank in the merged array. These elements partition the arrays and into equal-size subproblems which then can be(More)
Wireless sensor network applications require both energy-efficiency and low latency for reporting urgent but rare events. Various wakeup scheduling schemes have been proposed to save energy by employing duty cycles and to reduce end-to-end delay by synchronizing nodes' wakeup times and shortening setup latencies. Most sensor applications incur a predominant(More)
Mobile Ad-hoc networks are inherently prone to security attacks, with node mobility being the primary cause in allowing security breaches. This makes the network susceptible to Byzantyne faults with packets getting misrouted, corrupted or dropped. In this paper we propose solutions using an unobtrusive monitoring technique using the “Detection Manager” to(More)
Localization, an important challenge in wireless sensor networks, is the process of sensor nodes self-determining their position. The difficulty encountered is in cost-effectively providing acceptable accuracy in localization. The potential for the deployment of high density networks in the near future makes scalability a critical issue in localization. In(More)
Bluetooth is a promising new wireless technology that enables portable devices to form short-range multi-hop wireless ad-hoc networks. Bluetooth Scatternet Formation is one of the challenges that needs to be resolved. In this paper, we present a new, distributed Bluetooth mesh scatternet formation algorithm. The generated scatternet is a connected mesh(More)
Wireless Sensor Networks (WSNs) consist of spatially-distributed autonomous sensors that can cooperatively monitor physical and environmental conditions. Because of sensors’ resource-constraints in terms of size, power, and bandwidth, one of the fundamental objectives in WSNs is improving energy-efficiency. In this paper, utilizing sensors with variable(More)
