The bandwidth limitation, node mobility, and multi-access interference characteristics of mobile ad hoc networks (MANETs) pose unique challenges to deploying a DHT in MANETs. Previously, we proposed Ekta, a DHT protocol for MANETs that seamlessly integrates a DHT and a reactive routing protocol to effectively overcome the above challenges. In this paper, we propose an enhanced protocol to Ekta, called Ekta+, that improves the DHT routing performance of Ekta by exploiting the high degree of route reuse characteristic of DHTs - the very same characteristic that makes DHTs highly scalable. In essence, Ekta+ multiplexes (aggregates) many DHT messages (typically small packets) that share physical paths at clustering points which occur naturally in DHT routing. The multiplexing of multiple small packets into a single larger packet allows Ekta+ to reduce control overhead and interference which are critical to good performance in a MANET environment. We present the design of Ekta+ along with a preliminary performance evaluation using a detailed wireless network simulator.
