In wireless ad-hoc network, one of the reasons that increases the data packet loss rate is the gray zone effect. The gray zone effect can happen when broadcasting control packets with lower rate while transmitting the data packets with such higher rate or the same PHY data rare. This leads to nodes are able to find valid routes but some data packets may not reach the destination, which causes the high packet loss rate. Most research efforts so far have attempted to modify the routing protocol to take the gray zone effect into consideration. But this method could have a detrimental performance owning to its high computational complexity. In this paper, by adjusting the suitable broadcast rate and data transmission rate, we can obtain the high throughput than the original way. By simulations, we show that our novel approach can achieve the best throughput. |
