Bargaining based Design Mechanism for delay sensitive tasks of mobile crowdsensing in IoT
Ahmad Waqas,Ullah Ata,Sheharyar,Jhanjhi N.Z.,Ghoniem Rania M.,Brohi Sarfraz Nawaz 한국통신학회 2024 ICT Express Vol.10 No.1
Internet of Things (IoT) is getting growing interest to offer great opportunities in combination with Mobile Crowd Sensing for real-time applications. Existing approaches motivate mobile workers (MWs) for approaching the distant locations to receive attractive incentives for traveling. The main question addressed is that a number of tasks remain incomplete out of total al-located tasks. Moreover, the profitability and feasible budget constraints of the platform is also not considered. This paper presents Bargaining based Design Mechanism (BDM) to involve the nearest located MWs to improve the completion of tasks. The main method involves a bargaining based game model that increases the task completion ratio while considering the feasible budget constraint, platform profitability and social welfare. The proposed approach comprises of two algorithms: one for the selection of optimal MWs with low cost and less delay. Second is to organize bargaining for rewarding the platform on social welfare. Our work is validated by developing a testbed on Windows Azure cloud. Results prove that proposed BDM out-performs the counterparts in terms of decay coefficient, task completion ratio, participant’s winning ratio, fraction of task incompletion and social welfare.

Phytochemical investigation of the whole plant of Amberboa ramosa led to the isolation of six sesquiterpene lactones which could be identified as 8α-hydroxy-11β−methyl-1αH, 5αH, 6βH, 7αH, 11αH-guai-10(14), 4(15)-dien-6, 12-olide(1), 3β, 8α-dihydroxy-11α−methyl-1αH, 5αH, 6βH, 7αH, 11βH-guai-10(14), 4 (15)-dien-6, 12-olide (2), 3β, 4α, 8α-trihydroxy-4β-(hydroxymethyl)- 1αH, 5αH, 6βH, 7αH-guai-10(14), 11(13)-dien-6, 12-olide (3), 3β, 4α, 8α-trihydroxy-4β- (chloromethyl)-1αH, 5αH, 6βH, 7αH-guai-10(14),11(13)-dien-6, 12-olide(4), 3β, 4α, dihydroxy- 4β-(hydroxymethyl)-1αH, 5αH, 6βH, 7αH-guai-10(14),11(13)-dien-6, 12-olide(5), 3β, 4α-dihydroxy- 4β- (chloromethyl)-8α-(4-hydroxymethacrylate)-1αH, 5αH, 6βH, 7αH-guai-10(14),11 (13)-dien-6,12-olide (6) by spectroscopic methods. All of them showed inhibitory potential against butyrylcholinesterase.

Indigin, alkylated xanthene (1) and indigoferic acid (2) have been isolated from the chloroform soluble fraction of Indigofera oblongifolia, along with $\beta$-sitosterol (3) and 3-hydroxybenzoic acid (4), which are reported for the first time from this species. Their structures were determined through spectroscopic techniques. Both the new compounds 1 and 2 showed significant activity against enzyme lipoxygenase, while 2 further showed moderate inhibition against BChE.
