Assurance networks are designed to realize trustable\nInternet-Of-Things including terminal devices/infrastructure\nservice applications for new generation networks.\nTo construct assurance networks, it is necessary to evaluate\nthem quantitatively. In this paper, we provide one of case\nstudies to evaluate them quantitatively. In mobile ad hoc networks\n(MANETs), the network environments change over\ntime due to the movement of nodes, the battery level of\nnodes, and so on. Assurance networks must maintain high\nperformance even when such diverse changes of the network\nenvironments occur in the widely applicable domain. And if\ntheir performance degrades, they must early recover from\nthe changes. So far, we have proposed a routing method for\nMANETs, called Route-Split Routing (RSR). RSR can suppress\nescalation of control packets in large scale MANETs.\nHowever, with RSR, drawbacks occur when some nodes exhaust\ntheir batteries. In this paper, we propose a sustainable\nroute-split routing scheme to improve assurance by adapting\nnode faults due to battery exhaustion for MANETs. To\nevaluate the assurance of the proposed method, we have implemented\nit with a simulator and have conducted simulation\nexperiments. The results indicate that the proposed method\ncan maintain high throughput when some nodes experience\nvarious levels of battery power and power consumption and\neven when some nodes die simultaneously.
