The applicability of existing DTN architecture and routing protocols are limited to only mobile node environment. We believe that DTNs custody transfer and hop-by-hop routing capabilities give a full potential of flexibility, adaptability and simplicity for wider range of different characteristics of network. To realize this, first, we propose a single unified Bundle Protocol (BP) layer where BP is a generic and universal protocol with the message format and protocol sequences independently of network characteristics like infrastructure-based or infrastructure-less network. Secondly, we propose an integrated DTN routing scheme, called HALF (Handoff-based And Limited Flooding) that combines a handoff-based routing protocol with a limited flooding technique like Spray and Wait protocol. In this paper simulations have been carried out to compare HALF with the existing protocols under a wide variety of network environments and conditions. The results indicate that HALF can achieve higher delivery ratio and lower latency under broad network environment.
