— We present a new 3D mesh codec for mobile devices. Mobile devices have limited resources such as low memory, slow CPU speed, low power, and no floating-point processor. Considering these mobile characteristics, we suggest a new approach: a hybrid of a progressive geometry and a single-rate connectivity coding. By this approach, our algorithm achieves fast(More)
In this paper, we focus on an energy efficient position-based three dimensional (3D) routing algorithm using distance information, which affects transmission power consumption between nodes as a metric. In wireless sensor networks, energy efficiency is one of the primary objectives of research. In addition, recent interest in sensor networks is extended to(More)
In this paper we propose a challenge-response protocol called: DCSTaR, which takes a novel approach to solve security issues that are specific to low-cost item-RFID tags. DCSTaR protocol is built upon lightweight primitives such as 16 bit: Random Number Generator, Exclusive-OR, and Cyclic Redundancy Check and utilizing these primitives it also provides a(More)
