AORA measures the network＇s traffic information including delivery time, route energy etc. by the continuous delivery of data packets, then calculates the compositive parameter for each route which can be seen as the stigmity and uses it to choose the comparatively optimal route in real time. To adjust the weight of each traffic information, the algorithm can meet the different demand of the network＇s user. Multipath source self repair routing （MSSRR） algorithm and dynamic source routing （DSR） can be seen as the special samples of AORA. The routing overhead is not increased in this algorithm. By using simulation, it can be seen that the performance of AORA is better than that of DSR in all scenarios obviously, especially the delivery fraction is increased by more than 100 96.展开更多

Global routing structure may also produce extra processing cost because the dynamic topology will introduce frequent exchange of routing vector or routing state between nodes. To deal with these problems an improved multicast protocol based on routing grid is designed to ensure that the muhicast packets could be sent to destination through dynamic topology network using muhicast routing grid.展开更多

文摘Problems may occur in ad hoc network when packets are being multieast. Global routing structure may also produce extra processing cost because the dynamic topology will introduce frequent exchange of routing vector or routing state between nodes. To deal with these problems an improved multicast protocol based on routing grid is designed to ensure that the muhicast packets could be sent to destination through dynamic topology network using muhicast routing grid.
