註釋Broadcasting as mentioned in the introduction of the chapter is a very essential operation in wireless ad hoc networks. It helps not just in route discovery but also in emergency conditions. Because of the constraints that the network being wireless and ad hoc at the same time, puts forward, finding an optimum solution is a challenge. Bringing in uncertainity into the system would be one way of optimizing the broadcasting operation. A more effective way to use this probabilistic broadcasting operation is to introduce some intelligence into the system. Intelligence in the form of neighborhood information, tranmission ranges would be very useful. In particular, if the network is very sparse it would make sense to use higher value of broadcast probability and vice versa. This idea has been explored in (Zhang & Agrawal, 2005). Another way to optimize the broadcasting operation is by ensuring that instead of having a common optimum tranmission range a variable tranmission range (Member-Gomez & Member-Campbell, 2007) could be used to increase the capacity (Gupta & Kumar, 2000) of the network.
