Abstract:
Broadcasting in Mobile Ad Hoc Networks
(MANETs) is one of the most important operations that are
used to disseminate data throughout the entire network.
Simple flooding is the conventional operation that performs
broadcasting in MANETs. Although flooding is a simple
operation that achieves a high delivery of data, it has many
disadvantages summarized by the redundant broadcasts,
contention and collision, which are referred to as the
broadcast storm problem. Probabilistic protocols stand to
provide a good solution to the problems associated with
simple flooding. This paper, presents Dynamic Probabilistic
Flooding (DPF) for expand Dynamic Source Routing (DSR).
The dynamic probabilistic routing protocol controls the
flooding by dynamically determining the rebroadcast
probability of a node based on the local knowledge of the
neighbors, thus reducing a rebroadcast messages, and
therefore, increasing the overall routing reliability by
decreasing the routing overhead. All experiments are
conducted using Network simulator 2 (NS-2). The
simulations results show that the proposed protocol
outperformed original DSR in terms of reducing average
End-To-End delay, increased PDR and reducing routing
overhead.
