Frequency hopping provides some protection against multiple access interference in random-access ad hoc networks. Power control and the use of short routing hops can further reduce interference by promoting spatial reuse. If the network is fully connected, frequency hopping and power control alone may be sufficient to allow good throughput without the use of routing. This approach is particularly...
This paper investigates packet acquisition in a random multiple access (RMA) environment. An analytical approach to performance evaluation is provided, which enables the waveform designer to set design parameters quickly such that the required performance is achieved without over-design. RMA is a medium access methodology used for time-frequency hopped signaling and has been widely considered in the...
It has been shown that throughput in wireless networks is enhanced by using scheduled transmissions, low transmitter power, and multiple short hops to relay a packet from its source to its destination. There remain several difficulties with this approach. For example, relaying over many hops can cause large packet delays. The routing and slot assignment protocols can also incur a large overhead penalty...
