%X In Wireless Mobile Ad hoc Network (MANET), collecting reliable global topology information is pro- hibitive. Thus without prior knowledge of network topology,Broadcasting provides an indispensable means of com- munication in Ad hoc networks. However,as radio signals are likely to overlap with others in a geographical area, straightforward broadcasting by flooding usually result in redundant retransmission,contention,and collision,referred to as broadcast storm problem. A number of routing protocols have been put forward recently to alleviate broadcast storm problem. But all of them either lack reachability and involve high computational overhead. This paper presents a Beamed Broadcasting Protocol that provides a new method of broadcasting with reduced retransmission,high reacha- bility,and low power and bandwidth consumption.
