Abstract : This memorandum proposes a simple mechanism for enabling basic delay tolerant networking with off-the-shelf MANET routing protocols - with the objective being to enable trading off slightly longer data delivery delays against resilience to a temporary lack of connectivity between a router and the ultimate destination of an IP datagram. As part of testing the benefit of said mechanism, an extreme network mobility model is proposed, entitled the "PopUp model": a router appears in the network, and operates normally - then may disable and disappear from the network to appear later elsewhere. Observed to cause severely degraded performance for MANET routing proto- cols, this model is used for testing the proposed mechanism in OLSRv2-routed MANETs. The proposed mechanism shows to vastly increase the data deliv- ery ration, with reasonably low increases in delays and control traffic overhead incurred.
