2014-2-11  During an aggregation process, whenever either the ASL or ATL limit of the associated transmission profile is reached, the aggregation process ceases and a data item is constructed. Within a data item, ADUs are grouped together based on the associated topic ID. Then, DTPC protocol appends the data item to the outbound transmission queue.

We propose three variants of IoB-DTN: IoB based on spa-tial aggregation (IoB-SA), IoB based on temporal aggregation (IoB-TA) and IoB based on spatio-temporal aggregation (IoB-STA). We compare the three variants with the multi-hop IoB-DTN protocol without aggre-gation and the low-power long-range , LoRa type. Comparison

With DTN as your partner, you will operate more efficiently, provide better customer service, and boost your bottom line. Nobody automates the process of shipping and storing fuel quite like DTN. Our terminal automation system is the industry gold standard. DTN provides you unmatched inventory control and extensive reporting capabilities.

In DTN, data are forwarded using "store and forward" method on the basis of bundles, a series of contiguous data blocks. ... There have been some DTN protocols for VANETs [15] - [19].

2014-5-12  like DTN, and the presence of sel fish DTN nodes could cause catastrophic damage to any well designed opportunistic routing scheme and jeopardize the whole network., Here to address the selfishness problem in DTNs, propose a practical incentive protocol, called Pi, such that when a source

2015-5-11  the energy consumption. By data aggregation we refer to the process of taking information from multiple bundles, combing them using an aggregation function and to forward only a single bundle to the next hop. As we will show in the following Section II, existing data aggregation approaches are often based on a specialized network structure.

2019-8-6  the aggregation of the contacts into a social graph. We can have 2 different aggregation schemes: • Time window based aggregation – The past seen contacts are collected over a time frame for e.g. consider all the contacts seen in the last 6 hours time frame.

This process is conditioned by the existence of sufficient buffer capacity and energy in nodes. ... This is the goal of in-network aggregation protocols ... DTN routing protocols need to be ...

2018-6-1  The aggregation time is set to 10 min, while the spread time set to 90 min. In every simulation experiment, nodes perform aggregation and spread operations alternately and continuously for 3 h. Throughout the whole process, nodes in group A keep sending messages to nodes in group B at a fixed rate of 12 messages per minute. The expiration time ...

2015-2-4  which makes data forwarding in DTN extremely difficult. To address this problem, researchers have proposed approaches to exploit social network concepts such as centrality [2][3][4], community [5][6][7][8] and friendship [9][10][11]. Community has received considerable attention because of its applications to data forwarding in DTN, worm ...

2010-4-30  Remote resolution: these methods are for sending/receiving resolution requests and responses to/from a remote DTN node (since the process is asynchronous). Note that the local resolution API will be exercised at the remote resolver nodes before they send a resolution response to the requester. Methods for distributed name KB management:
