Wireless network access protocols can assist nodes to conserve energy by identifying when they can enter low energy states. The goal is to put all nodes not involved in a transmission into the doze state. However, in doing so, one must tradeoff the energy and other costs associated with the overhead of coordinating dozing with the energy savings of putting(More)
We propose a novel medium access control protocol for ad hoc wireless networks called Synchronous Collision Resolution (SCR) 2. The protocol assumes that nodes in the network are synchronized, thus, nodes with data to send can contend simultaneously for the channel. Nodes contend for access using a synchronous signaling mechanism that achieves two(More)
Increased demand for electromagnetic spectrum (licensed and unlicensed) has spurred the development of sharing techniques based on databases and the development of FCC rules requiring them for TV Whitespace bands. These concepts are also being considered for other sharing scenarios. Many standards groups have already begun standardizing solutions for TV(More)
In this paper we describe a new simulation tool used to study the creation and optimization of propagation maps for Node State Routing protocols within wireless and mobile ad hoc networks. The simulation is developed in MATLAB and interfaces with DLL libraries for network data management support. These DLL libraries also have applications within OPNET for(More)
