چکیده
MORE (MAC-independent Opportunistic Routing & Encoding) could increase network throughput by using network coding. On the other hand, directional antenna has better power efficiency and introduce the possibility of space diversity. In this paper, the authors try to combine directional antenna with opportunistic routing protocols and tried to use Network Simulator version2 to simulate it. The results show that there is an optimal lobe width for each particular circumstance and that under this optimal condition the throughput of opportunistic routing with directional antenna is much higher.
