Abstract:
|
Broadcast transmission mode in ad hoc networks is critical to manage multihop routing or providing medium access
control (MAC)-layer fairness. In this paper, it is shown that a
higher capacity to exchange information among neighbors may be
obtained through a physical-MAC cross-layer design of the broadcast
protocol exploiting signal separation principles. Coherent
detection and separation of contending nodes is possible through
training sequences which are selected at random from a reduced
set. Guidelines for the design of this set are derived for a low
impact on the network performance and the receiver complexity. |
