چکیده

A Markovian model i s formulated to find the throughputdelay performance for slotted-ALOHA multihop packet radio networks with a fixed configuration of packet radio units (terminals and repeaters) and.fixed source-to-link paths for packets. Improvements in performance which are obtained by the adjustment of transmission parameters (suppression/acceleration) according to the states of nearby units and/or by having repeaters equipped with multiple buffers are demonstrated.

The Spatial Capacity of a Slotted ALOHA Multihop Packet Radio Network with Capture

A bstract-In this paper we determine throughput equations for a packet radio network where terminals are randomly distributed on the plane, are able to capture transmitted signals, and use slotted ALOHA to access the channel. We find that the throughput of the network is a strictly increasing function of the receiver’s ability to capture signals, and depends on the transmission range of the ter...

Relation between transmission and throughput of slotted ALOHA local packet radio networks

Abstruct-A new method for the exact calculation of the throughput of a centralized slotted ALOHA packet radio network over slow Rayleigh-fading channels is presented and the results are compared with the computer simulations. Also, upper and lower bounds on the performance are provided. The effects of capture on the throughput of the system are related to the modulation and coding technique, si...
